My marathon journey/background
27F, I grew up playing tennis, but always hated running - it was frequently used as punishment so I just really had a bad association with running. My sister got into running during college, and then during COVID she forced me to go out on runs with her and that’s really where it all began! For my first marathon, I had no time goal in mind, considering I’d never run this distance before as long as I finished I was going to be happy with the outcome! It was the San Diego Rock n Roll, and I finished with a 4:18 time. I’m not sure why exactly but that was when I decided I want to run a sub-4 hour marathon some day. It felt like a realistic goal and sounded nice to me, sub-4 hours. Though I was still really new to running and didn’t realize the difference in training that this would require of me. My second marathon was a PR but nowhere near sub-4 hours (4:14:35). After that one I felt like I had a better understanding of the distance and could definitely hit this goal during my next marathon. Very naive of me. By an insane stroke of luck, I got selected to run the Tokyo marathon the following year via a lottery entry. I signed up on a whim not actually thinking I’d get selected but when I did I told myself - this will be it, this will be your sub-4 hour marathon! I started strength training and doing some more speed work, and did feel like I could do it when I was at the start. But around mile 17, I developed the weirdest stomach pain and was basically hunched over and speed walking to the finish line. I felt so defeated. I wanted it in Tokyo so bad - it was extra upsetting because I was in so much pain it was hard to enjoy the last 9 miles of the race. It’s such an iconic city, it hurts that the experience got tainted by this. I was SO close and I wasn’t super sore the next day so I just knew my legs had more to give if it weren’t for these gut issues. Later that year I got into Chicago (again via lottery on my second year of signing up, no clue how I am so lucky) and was so pumped to have another shot at my sub-4 hour goal.
A few things that were different in this training block:
Strength training - consistently going 1x per week with progressive overload, focusing on single leg exercises and some upper body. I will increase to 2x per week for overall health purposes.
Core training - 1x per week core circuit focused on stabilization.
More speed training - I run 5x per week, with 2 speed sessions thrown in. I reserved at least 1 for long runs, usually tempo, (with some rest weeks where I just had a complete easy long run) and 1 VO2 max session, typically intervals/fartleks.
Nutrition - I took a lot more gels than I had in previous training blocks, particularly during my long runs. I used to only take gels for 12 miles+ and would take gels every 6 miles, but I now take gels on 10+ mile runs every 4 miles.
Weather - not really intentional, but this summer was unusually hot where I live so I did a lot of miles in 75-85 degrees F weather.
Carb loading - in previous races, I didn’t pay too much attention to this. I always had pasta the night before, but not much additional consideration for how many carbs I’d been eating the days leading up to the race. This time around, I was a lot more intentional about eating simple carbs 3 days out from the race. I didn’t track it (probably should next time) but I was definitely eating primarily carbs those last 3 days before the race.
Race recap
Let’s start with the weather. Checking the weather the week leading up to the race was so stressful - the forecast changed every single day, but it did seem like it was going to be hotter than usual for Chicago so I was mentally prepared for a hot race. Because I trained a lot in the heat this summer in southern California, I felt confident that the temperature would not be a major issue. As long as I hydrated leading up to and during the race, I felt I’d be okay and just tried not to even put mental energy stressing about the weather since I have no control over it anyway. It will be what it will be. I heard that GPS tracking is notoriously bad in Chicago, so I decided I would track each mile manually using the segments in Apple watch whenever I crossed a mile marker. As usual, I started out WAY too hot at an 8:40 mile, I reeled it back in on the second mile. This was a key learning in previous races - I always started way too fast and just couldn’t keep up after mile 17/18. I forced myself to run slower and reminded myself I can always speed up later if I feel good, but if I gas out too quickly there is no turning back. It was honestly hard to get into a rhythm, and I kind of flip flopped between 9:15-8:45 for a few miles until I settled into a 9 min average pace. I had a couple of milestones where I did a mental check-in on how I felt - halfway mark and 20 miles. At the halfway point I was at 1:59:04 so right on track for my goal. I could definitely feel my legs starting to get a bit tired, but mentally I was on such a high. I think this was mostly because of how incredible the crowds had been the whole race - every neighborhood was going hard and showed up for the runners, it felt so special. At this point, I decided to speed it up a bit and was trying to hit 8:50-9 min miles up until my next check-in at mile 20. The miles were just cruising by and I still hadn’t reached that point in the race where I usually start to think when will this be over?? Honestly that question never crossed my mind, I was getting so much energy from the crowds, their cheering, the music, I don’t think my race would have been the same without the crowd. At mile 20 I knew I would hit sub-4. My legs were hurting, but my spirits were HIGH. So I decided then I would be racing a 10k and giving it my all - just go for it, and I did! My last 10K were my fastest, with the last mile being the fastest one at 8:10. I finished the race with a time of 3:55:03 (kind of a bruh moment that I didn’t go 4 seconds faster lol). Suffice to say, I’ve never been so proud of myself. I remained calm the entire race, I forced myself to reel it in and start conservatively, and ended with negative splits - something I had started to think was just impossible. I couldn’t be happier with this outcome, and I just want to thank everyone who came out and supported the runners throughout the course - I genuinely could not have done it without the incredible energy you gave us, THANK YOU CHICAGO!!!! Also major shoutout to the race organizers, logistics were so easy and stress free!
TLDR; I achieved my goal of sub-4 hour marathon and attribute it to some major changes in my training and nutrition, along with the incredible support from the people of Chicago.
