I completed W4R2 first thing this morning. I wasn't looking forward to it very much as I found W4R1 quite testing. However I was delighted to find todays run alot easier. The only difference I can see was that I did R1 in the evening. Do fellow runners tend to find the time of day they run to make a difference to their permformance or not?! What is the most popular time of day to run?
