Justwondered if any of you exerieinced runner can help. I ran my first marathon in New Yorks a few weeks ago on a plodding "Get Your Round" programme. Long runs were no problem ut whenever I tied to run faste or add speed sessions I found he muscles on the front of my thighs were very sore and tight for days after. I had warmed up an stetched before. I have got a place in the London Marathon and want to run under 4hours 30 minutes.
