6x400s

Today was a gorgeous day....but I did my 400s on the treadmill. Which was okay, really - I prefer it for things like that.

I also put a 0.5% grade on it to better simulate "real" running...or something.

My times (after a 0.75-mile warm-up):

2:19
2:26
2:25
2:23
2:23
2:21

306 cal
2.3 miles total

I think I'll do a 5-mile tempo run rather than 6 miles...and maybe do it tomorrow. It's supposed to be another really nice day.
