Ok, so got through week 2 just about unscathed.. slight pain in one calf. But found in each run that some running times felt ok albeit at my pace (8.5km on treadmill) whilst others felt like I wanted to slow down after a few seconds... there is no constant pattern....i.e. today run 3 the second and fifth were really tough other ok!
Any thoughts? is it just me getting used to running after nothing for many years?
