I finished with 3:54 so met my sub-4:00 goal. Overall happy with that result but a tiny bit frustrated that I was on pace for a better finish and I struggled heavily in the last 5-6 miles. Here is my pace breakdown: There was a big elevation gain mile 20-22 so that took its toll on me and then I was just gassed afterward. In my previous marathon in February, I had a knee problem around mile 20 and similarly struggled down the home stretch, but I guess because my knee was bothering me, that pain superseded any feeling of hitting the wall from a physical exhaustion standpoint. I felt like my training was reasonably good. Long runs were 13, 15, 17, 19, 11, 20, 13, and 11 miles in the 2 months leading up to the race. I wonder if I should work towards a 22-23 mile run at the peak of training? Most training plans seem to stop at about 20 miles. I wonder a little bit about my nutrition and hydration. I eat whole grain pasta the night before, then a banana and a bagel with peanut butter the morning of, then I eat GU gels and drink Propel/Gatorade during the race. I think I had 5 gels yesterday, about mile 5, 10, 14, 20, 23. The 2nd/3rd ones didn’t go down super smooth so I got nervous about having more, but perhaps I should’ve forced them anyways. Normally I tolerate them just fine. Open to any suggestions. I’ll probably give it another shot sometime next year and try to get 3:45.
