Pain in the thighs question.(3 posts)

Pain in the thighs question.muncher
Apr 15, 2002 5:44 AM
On sat I ran for the first time since badly damaging my ankle in Jan (week on crutches, lots of physio).

I have been riding a lot in the meantime (only lateral stability was badly affected, so cycling has been fine for about 8 weeks luckily) and done some high-milage rides - 70 milesish - no probs.

However, despite a modest pace (7-8 min miles) over only 4-5 miles of mainly soft ground, and a very thorough warm up-down my thighs are completely shot, with a bad dose of the stiff, burning quads situation.

Question is - what causes this? Is it an internal brusing of the tissue of some kind? A build-up of some nasty stuff in the muscle fibre? Minute tearing of the muscle fibre?

Question 2 - is it avoidable by doing anything that I didn't do - or do you just have to grind through it?

Thanks.

What you're experiencing is most likely the normal soreness from starting running. The eccentric motion of the thighs in the running gait cause more trauma (micro tears) than cycling (concentric motion). It will get better with time. After a couple weeks it will be no problem. Make sure you're drinking a lot of water, stretching, and doing massage.

Running on softer surfaces can help minimize the im[act (which also reduces the eccentric contraction), but it won't totally eliminate it (and it will increase the stress on the calves).

4-5 miles may not sound like much when youre used to a large base, but face it, thats a pretty good distance after a 4 month (complete) layoff.

might just have been a little too big a jump.
