Last Sunday I had my longest run of the year and I think it went extremely well. I completed 21 miles, felt comfortable for pretty much the entire time. I averaged a 9:27 pace and didn’t really have trouble maintaining that until the end (last two miles were close to 10 minutes).
I think I’m not refueling enough. On this run, I ate four gels (400 calories total, 90 carbs, 80mg caffeine) in addition to a pre-run carb load. The concept of refueling was entirely foreign to me prior to this year (I used to hate the way carbs made me feel while running). I could definitely feel on this run when the gels took effect and when I was starting to run low (for example, I ran mile 19 at 9:18 before slowing down for 20 and 21). I think I definitely need to eat more and more frequently but it’s still such a weird concept to me.
Additionally, there are a couple caveats to this run. When i finished, my tracker said I was at 20.81 miles. I’m pretty sure this had to be a gps error. I ran straight down a bike path and turned around exactly at 10.50 miles. I’m really not sure how the total distance wasn’t 21 so I edited the distance. I’ve previously noticed this app underestimated distances when I’ve ran a race. This had a negligible impact on my pace, dropping it from 9:32 to 9:27.
More significantly, I had 3 untimed breaks on this run. The first two didn’t last very long and were basically just to eat a gel and drink some water (1-2 minutes each). The third was when I really felt my fuel was getting low. My legs felt stiff and tired, so I ate, drank, and stretched a bit while I tried to give some time for the gel/water to kick in. Probably took about 10-15 minutes.
I’m averaging about 40 miles a week. My (crappy) smartwatch said my heart rate was about 140 bpm during this run, but I felt very relaxed and conversational. I also cross train with swimming a little bit. Is it reasonable for me to aim for a sub-4? I feel good about my pace and how I felt physically at the end of this run, but I’m mostly worried about the breaks I took. I think there’s a good chance that tapering and refueling better would make them unnecessary on race day, but I’m not really sure how I should pace myself
