Hi LRC,
Just did a 40-minute tempo run at 6:43 pace.
Paced basically perfectly: even, felt easy at halfway, moderately challenging at 30 mins, and tough at the end, without ever pushing too hard.
In two days I'm going to do a 20-minute tempo. I've read loads of definitions, still not sure how fast I should go.
Guessing 6:30 pace would be a decent estimate?
