In today's July 4th 4.5 mile race, I had a surprise win in the Master's division (40+). Only held an 8:55 pace, so there clearly weren't any gifted older runners, but at 53 YO and 82 degrees and no longer running distance, I'll take it!
I switched from marathoning to sprinting about 18 months ago, and as my 5K time has gotten slower, I've noticed that my max heart rate has gone up. My top racing heart rate was about 180 two years ago. Last July 4th, I peaked at 188, and this year I peaked at 192 (2 weeks after a 100m PR). I've lost 1 - 2 minutes off my 5K, but the max HR now goes 12 - 15 bpm higher at "redline." Pretty good evidence that the sprint training has changed the max intensity level, while reducing endurance. There may be something in here for the younger runners to learn, like be sure to put some max effort sprints into your regimen.
