Speed sessions

[Deleted User]

I train at a pace of about 9:30/10:00 miles, I do about 25/30 miles a week. What my problem is that when I decide to do so speed sessions I get pain in both my hamstrings. I have trying interval training tempo fartlik etc but every time I try to go faster than what I plode along at I seem to get this pain for a few days after. Anybody got any ideas what I'm doing wrong. I warmup for 10/15 mins and warmdown fo rthe same?? Any ideas please????

perhaps you should start with usual pace to warm muscles up then stretch them out PROPERLY ie 3 sets of 15 to 30 seconds. Then do your speed stuff. Thenwarm down with your usual pace before finally stretching them out.. Might work but I am a bit lazy at this myself and don't I suffer!
