IBM 10K race. T=73-76 degrees. Humid 75%. Slept 7 hrs. Woke up 2.5 hrs before race time. Well hyderated. Good relax warm up for 2 miles. Drills. Ran 6.2 miles at 7:36" AVG Warm down 1 mile. To qualify for Boston I would need to run a 3:30:00 marathon or for a 10K I would need to run at 7:12 pace. My last 2 miles time trial at 6:50 pace suggests that I potentially could run a marathon at 3:36:18 or a 10K at 7:24 pace. And that was my goal for this 10K. I did not have a watch on me so the first 2 miles I was running at about 90-91% effort which seems pretty comfortable to me. Everything works as planned. I felt like I could keep going at this pace for 6.2 miles. The official clock said 8:30 for the first mile but I had a late start so it doesnt tell me much about my pace. I felt like I was running at about 7:20-7:30 pace. I learned later I ran the 1st mile at 7:39" pace. Going into the 3rd mile, with a little bit of incline, my body started feeling the heat. My legs and my heart (rate) started working harder and harder to maintain the pace and keep up with the group that I had been running with. At about 3 mile mark, I was sweating a lots and my breathing became uncontrollably hard (95-98% effort). I was forced to slow down and take a 30 meters walk break during the water stops. I slowed down even more during mile 4th & 5th, forced to take some additional walking breaks beside the usual water stops and it was so painful that I was seriously thinking of quitting. However, running slower allowed me to recover a little bit. I also felt a little bit better mentally and start picking up the pace on the last mile (second wind?). The downhill plus the thought of finishing the race really helped to carry me on the last mile. I probably ran the last mile at about 7:10-7:20, thanks to the strong finish on the last 400 meters. I was totally spent at the end. I am very disappointed that I ran my 10K at 7:36 pace, not at 7:24 pace as planned, or 7:12 as required for BQ. The only little consolation is I usually ran at about 8:00 pace for a 10K in October then ran a February marathon at 3:45:00. Should I focus more on endurance/MGP/tempo runs and less on speed? Your advice is greatly appreciated. |
