More MP 5 ks

Calfs felt shot after yesterdays run and then a long deep massage on them last night. The warm up didn't warm them up but still decided to do the session. Two 5k's at Marathon Pace : 4.15 per k/ 21.15 for 5k. Surprised to do 20.58 + 21.03 - (5 minutes break in between)better than last Saturday but then again I am not trying to get faster just do them at the set pace - no slower no faster.
