I'm training to walk the marathon this year, and I've noticed that in the last few weeks every time I pass the 13-mile mark or so I develop an increasing overall soreness/ache in my legs. It's just about everywhere--buttocks, thighs, calves, feet--, from my waist down, most noticeable in the larger muscles. The farther I go, the worse it gets. The ache persists after I stop, and gradually diminishes over the next 2 or 3 days.
It doesn't feel like injury/tendonitis pain, more like a deep, generalized muscle ache. More of an ache than a burn. It doesn't feel like cramping. It's gone well before I'm due for my next long walk.
Everything else is going great on the long walks--toward the end, my overall energy is good, I'm staying well-hydrated, etc. I'm slow--averaging about 15 or 16-minute miles. I'm a bigger guy, nearly 6' and 220 pounds. I add calories with gel packs and alternate Gleukos and water over the course of my long walks.
This ache worries me, in terms of my ability to finish longer distances. I can knock it back a bit with some tylenol or advil for the last few miles, but the end of my last long walk was pretty tough in terms of the pain.
I'm new to endurance excercise--is this normal? Can I expect this to get better as I stick to my training schedule and get closer to the marathon? Or is there something I'm doing wrong/missing? Any thoughts would be really helpful. Thanks!
