Second run this evening, was not looking forward to it firstly because of the weather and secondly my quads were still delicate from first run.
Put my gear on with my bobble hat ,started my music and synced mapmyrun and went for it. even though it was still hard work I found around the mile mark it started getting easier.
Finished and felt that I could go more but baby steps is fine at mo.
Hopefully the muscle burn will ease with time. Off for a nice hot soak now
