Apparently, BBA has built a track in Manchester! I'm pretty excited by this.
Excellent! Both the Chester and Springfield tracks have a good rubberized surface, but they're a longer trip. Note, however, you can't use them during school hours (7:35 - 2:30) per state regulation. Check out the rules for Manchester before you make a trip down. Sometimes you can get special permission. And forget it if they have an athletic event going on.
in the 40s...be careful!...or you'll get a flat tire. Spring fever. I remember 2007, when 85 or so was possible for 400. And one day, there was an ominous leg pull in the 42 sec 200, maybe the 4th. And, time revealed, that the upcoming USOC in Virginia (autumn) was crossed off the list.
Begs the ? at what % effort should one attempt to function, in speed work particularly, at say over 65 or 70 to ensure being ready to go again and again? Speed in O - sprints, what else? True one can't be a slug and get results. But back to be careful. And one can't leave out flexibility, and loosening up/stretching.
All true. What’s the right balance point? Will keep experimenting and try to figure how to do it while minimizing downside risk and disaster.
