I'm on week 4, and did the 2nd run last night. I seem to be coping in terms of my breathing, my calves/hamstrings are fine and I haven't suffered from stitch or shin splints. However, I have been getting close to stopping because of the pain in the muscles at the front of my thighs while running. It settles almost as soon as I stop, and strangely, it stopped when I ran faster at the end of last night's final 5 minute stage. I am only running at a very gentle jog (I can walk faster!). Is it possible that the slow jog is the problem? Do I need to run faster? Or is there a more logical explanation?
Advice is badly needed, especially when I look at what's ahead in week 5!
