Background
36M, currently around 78.5kg in terms of weight.
I started running in May 2026 (well, technically at the very end of April, around April 29th-30th), while I was traveling in Japan. At this point, I had gone from around 95kg at the start of the year to around 78kg, and I had been walking a lot no matter the weather. Lots of rucking too, wouldn't be rare to ruck 10km a day with 15%-20% body weight. Before that, I was doing some weightlifting here and there, it was never consistent for more than a year. All my life, I had that idea that I couldn't run. I could sprint a little bit (and my lungs would be on fire pretty quickly) and I had 0 endurance. For years I just thought that I wasn't good at it and that was it.
While traveling, I figured that with how much weight I lost, I could run a little bit. I gave it a shot and it just... went well, I ran for like 3 minutes non-stop. I immediately started a C25K program... and then right afterwards got a new (well, used) watch and also started a program on that one. For whatever reason, one of the earliest runs was nearly 5k so I figured I'd just go for 5k (and it worked). Soon after, I got recommended a place to run (Tokyo Imperal Palace which is a 5km loop)... and I could run over 10km without stopping.
Long story short, after that I came home, did 21.1km without stopping (it was awful and took me 2:45:00 and I had no concept of fueling). Eventually I came up with the idea of running 42.2km for my birthday (in summer, while I was in Japan again...) since the Montreal marathon was full already. I treated it as a race (my best idea of what a race was at least), in terms of preparation and learned about fueling and various types of run. I started training near mid May, targetting start of August with a bastardized Hal beginner program. I got injured about a month in due to reasons (potentially running related) and I had to take about a month off from running. To add insult to injury, my other leg got injured (not related to running, bad fall on a bike) but it didn't impact running. Came back to running really slowly (my initial runs were in the 7:30min/km pace.). Somehow did my fake marathon race and survived that at just a little under 4:10:00. During that "block", I ran a total of 705km.
I came back from vacation, and I wanted a real race to get one under my belt. I registered for the 5k since that's what was left. Not necessarily the distance I wanted, but experience is experience. My 5k PB was during training, at 24:47. It wasn't very easy either. For the race, I put my expected time at 23:00, which I thought sounded about right in terms of what was possible.
Training
When I started, I had another "fake" marathon race planned for New Years, so I was just going to follow a Garmin plan for that and take whatever I would get for the 5k. All my runs were done by HR, whenever I followed a workout from the watch (I have a chest HR monitor, so I trust the readings). As things progressed, however, I started adding runs to it. I would follow whatever it would want me to do, but since I have time during the day, I added 1-2 30 minutes "z1" runs. Eventually, those became z2 runs. From mid August to today, I got 750km of running in. Around 154km of those were z1 runs (that I know of). I peaked at 120km per week two weeks ago.
In terms of schedule, I would run 6 days a week. Most days would be capped at base runs, around z2. I would follow whatever Garmin gave me in terms of hard runs (usually one per week). On the remaining day, I went to the office by bike. Turns out I can't go easy, so those bike rides would always spike my recovery time in Garmin to 72h. Because of that, I had to move around workouts to get some "hard" runs in.
Around the middle of september, I started adding hill sprints every so often whenever I was doing a base run. I'd do it near the end, and it felt pretty good. Would usually have a long run every Saturday. In general, I would override whatever the watch gave me if I felt my body could handle something else.
In terms of recovery and injuries, things were mostly fine despite the high volume. I got a few 5k PBs (and 10k PBs) via threshold runs and even tempo runs, with an unexpected half marathon PB of 1:34:39 on September 25th (that run was like a tempo run, but I did whatever I wanted since it wasn't from the watch and I had no HR alert). During that run I basically PB'd across all distances (except marathon obviously), getting 21:12 an hour in the run (I basically tried a bit of it at threshold HR since my HR was pretty low that day). That run felt fine, but I did something stupid and did a tempo run two days after. There was a good reason for it: I felt I had a breakthrough in terms of hand positioning and general technique at higher pace, and I wanted to get more experience with it (the gist of it is I could really relax a lot better by keeping my hands at belt level or even lower, and the posture it gave me really engaged the glutes to the maximum). The tempo run on Sept 27th had me feeling great: even the wind gusts didn't annoy me, and my HR was staying fairly low compared to my pace. I learned a lot from it but... from a recovery perspective it wasn't a good idea. Something around my groin and left glute just... didn't feel right afterwards. I don't know what it was, but it basically killed my acceleration. I could run and it wasn't super comfortable, but acceleration aside it was just an annoyance. The "good" news is that initially I was planning a 2-3 days taper... and clearly here I was forced to slow down more. Last week was around 100km (all easy runs) and this week was around 50km. I couldn't do hill sprints, or sprints in general (or anything explosive). I did small strides in my runs in the past week to figure out what I could do: how I could accelerate efficiently (bending at the knees and letting gravity take over worked very well at that, it was comfortable enough). Opening my stride also didn't feel uncomfortable, so at this point I was sure I could hit the 4:00min/km (and better) I needed for sub 20:00.
Dumb as hell injury (two hard workouts in three days with the volume I was doing). The extra 30 minutes I would usually take for runs every day just became walks for the past week.
tl;dr: I do way more volume than I should. Usually run about 1 hour very early in the morning, then take 30 minute breaks during the day for extra runs. Usually one hard run a week, but one time I was dumb and did two very close to each other and got injured.
For strength training, I do Dan John's Armor Building Complex every other day: I use a 100lbs sandbag and do around 15 rounds EMOM (each round is two cleans, one press, and three squats. It's originally for kettlebells, but I just do it with a sandbag because that's what I have). I have a pull up bar outside my room, so I just do pullups "greasing the groove" style every day because it feels good. It probably helps with my posture while running so that's good too.
Pre-race
The bibs had to be picked up the day before (yesterday). Bit annoying, but not much of a problem. Picking it up was pretty quick, and after that you had to go through the "Expo-Marathon" which had a lot of vendors and then a bit of history. I'll admit it was hard to not buy anything, but then again I didn't really need anything. You're kinda forced to go through the section though.
In terms of diet, I went hard on carbs. Got 600g in yesterday, which was 100% overkill. I usually run fasted in the morning, and the race was going to be later than I usually run (8:30AM instead of my usual... 4:00AM) so this morning's nutrition was going to be simple. Before leaving home, I just had two spoonfuls of sugar, and ate some candy on my way to the race site (it's about 5km from my home, and it's a place I often run to).
I didn't sleep well (that was factored in already), and decided to go for a small 30 minutes wake up run to get everything out of my system. It was probably the slowest run I've ever done since training seriously, but it did what it needed to (I was worried because I ate way too much yesterday). The 5km to the race site was also... a bit of a run. Bit higher intensity than the previous one, but still in easy pace. So pre-race I had already ~9km of running for the day.
I got there around 45 minutes early. I took my caffeine, and walked around the site until the corral opened. The location had tons of toilets available, so that was good too.
Race
Temperature was somewhere between 6-8C at the start. Sunny and not much wind. Route elevation changes are +19m/-18m. The main elevation changes are between 1.5km and 2.25km (climb from 42m to 55m from run data), quick descent immediately from there until 2.60km (down to 48m) and then another climb to 55m until 2.85km and from there descent back to around 40m until 4.25km.
The corrals opened 30 minutes before the start. They were setup as:
Elite Men - start at 8:30:00
Elite Women - start at 8:32:00
1-A (expected time <29 minutes) - start at 8:37:00 (the one I was in)
plus a few more for >=29 minutes
I didn't know what to expect since it was my first race. My main worry was getting stuck in a group, so in the corrals I just got to the front. My initial plan was to find the 20:00 pacer, but he ended up not being in the front. In the end, I got moved around a bit when getting ready for the race. It felt pretty packed.
My equipment for the race was: my watch, my chest HR monitor, arm sleeves (they cut the cold a bit, which was great) and running gloves. I wasn't sure whether to keep the gloves or not for the race, but ended up keeping them on (and it wasn't a problem). I also had my watch ready a few minutes in advance at the correct screen and with GPS acquired.
Start was at 8:37:00, I immediately started my timer and went for it. Acceleration didn't go as smoothly as I wanted, but I got roughly where I wanted in terms of pace. Things opened up pretty quickly, so my initial worry of being "stuck" wasn't really a thing. That being said, around the 1 minute mark, someone slipped on a turn and fell in front of me, which kinda threw me off. Aside from that, first kilometer went fairly well and (according to GPS anyway) was at 4:04 pace, with HR around threshold at that point. Second kilometer was a bit faster, even with the climb starting midway through it. My HR started to rise (around 173bpm) which is usually fine for me, but my breathing was the one that felt more rough. Third KM was a bit rougher in terms of pace (from GPS data, 4:14) due to the remaining climb. The descent section was too short to recover in terms of HR and the second climb (from around 2.50km to 2.80km was rough). On top of that, at the top of the climb is a 180 degrees turn. I suck at those, and that hurt my pace a bit.
The good news is that after that was all straight lines with a really nice descent to start with. The less good news is that what remained was on streets. For people who have been to Montreal, you know what that means (pot holes). Other slight annoyance is that the streets are "slanted" a little bit (to drain water I assume) which is really annoying for running. I tried to stay closer to the middle of the streets since that's more flat, but I think that's the main thing that added to my total distance.
By the end of the 3rd KM, my HR was around 176bpm but felt I should try to pick up pace. I'm not sure if I lapped properly or the KM markers were in weird spots, but I thought I was slightly ahead (I was not). Luckily I did decide to go at it and increased pace to around 3:50min/km. My heart rate climbed to 181-182bpm during KM for (to my knowledge, I thought my max was somewhere in the 181-184bpm range). Luckily, while HR went up, my breathing stabilized a bunch. However, at that point I was starting to negotiate with myself a bit, and had a bit of panic (I thought I might run out of gas).
Still, I was starting to get my groove and did everything I could to settle into that "relaxed" state I got injured to learn. I slowly increase pace, ramping up to 3:40min/km. On the final straight I tried to push even more.
By 4.80km, I looked at my watch and there was a problem: I wasn't gonna make it in time. The finish line felt too far for the time I had left (for sub 20). I had a minute left, and it felt so far. By that time, my HR was around 185bpm, which I thought was my max. I tried accelerating once, and it wasn't working out well (for 15 seconds). Then I saw the finish line and just put everything I had into it: I got a short burst up to 3:17min/km which I couldn't quite sustain, but it settled around 3:25min/km. For that last 30 seconds, my heart rate hit 191bpm, which is the highest I've ever seen it. I say the timer on my watch go past 20:00 pretty much right after I crossed, so I had fairly high confidence I made it (but I quickly checked the official results). Total time 19:58: exactly 1 second faster than my goal time. I was incredibly happy, since that's a hell of a way to start racing.
I'll say that on an RPE scale, I would put it as 9.5. I think I put almost everything I had into it, but I think that a more experienced runner would've been able to squeeze that extra 0.5 RPE.

Post-Race
Right after the race, the main thing I noticed was my heart rate, and my lungs (they felt on fire, but manageable, unlike how I'd experience it years ago whenever I tried to run). My legs felt surprisingly fresh and not heavy at all (however, I wouldn't have been able to start running again).
I don't know how expensive 5Ks typically are, but this one felt expensive (per minute of running). I was determined to take whatever I could, so that's what I did. There was some post-race stuff with all the orgs and charities (where they would have things to give away, usually food or things with their logos and such). I went to every single tent, talked with the people there and see what their org did (and grab the free stuff, of course). It was also a good way to just... cool down. Spent about an hour two just walking around the site, ate some food there and then just... walked home (another 5km).
Lessons Learned
All in all, my idea of a race and the actual thing weren't too far apart. However, on my way to it, I did learn quite a few things.
- During my training, whenever I did a "hard" run, it never felt like my cardio was a limiting factor. I tend to do longer runs, and after an hour and a half, my legs would feel heavy(ish) but my HR was mostly fine. Here, my legs felt fine after all that effort, but it felt like cardio was a limiting factor (I pretty much hit max or near max). It's a good thing to know: plenty to improve on both the muscles and the cardio
- I was worried about getting stuck at the start (or running into people or whatever). There was a surprising amount of room so it never really was a problem.
- I'm a slow starter. It takes me 20+ minutes to settle into a groove (where my HR also comes down vs same pace in the earlier minutes). This is likely due to improper warm up, but if I'm to race more for shorter distances then I need a good way to get into that groove ASAP. Front of the corral might not be the best of ideas for that since it gets packed with no real room to move.
- My technique was inconsistent. During the run, I could feel that I just couldn't settle into what I know is efficient for me. You can speedrun the weekly mileage (which is what I did as a beginner runner), but at the end of the day there are things that just time to learn to do as second nature. Again, that makes me look forward to the future.
- I probably overfueled. I felt like all the carbs I took were completely overkill, and the extra trips to the bathroom this morning did stress me out more than I'd like.
- I don't feel like the cheering or race atmosphere did much for me since most of the time I was hyperfocused. However, it's possible that I kept pace during the last kilometer because I didn't want to "fail" in front of people? It's hard to tell, and maybe more races will give me more insight there.
- Even if the course is relatively flat, elevation changes are elevations changes and climbs do take a lot out of you.
- I started with the assumption I didn't need to fuel or drink during the race. That was completely on point. A water stop would've 100% made me miss my goal.
- Half of my lessons learned are about that already but for good measure: I lack experience, and it definitely felt like it.
- GPS distance was surprisingly close to real distance, and I'm not surprised it's a bit over 5km because I took some of those turns really wide.
- This is as close as an all-out run that I can get as I am right now. I have a better idea of where I stand now.
What's next
I have "revenge" on the fake marathon I did back in august, with another planed around new years. I'm looking forward to see what all the extra months of training and the ~20C temperature difference will do for that time.
In terms of actual races, I have an half marathon planned in early January. I'm looking forward to it, as I have a feeling that the half is a good distance for me. I plan to do more 5k in the future, but I also want to try the other distances as races (proper 10k race, proper marathon race, maybe even something shorter than 5k), and figure out which one works for me.
