On my run today I noticed a big grassy hill and decided to run up it a few of times. I may be under instructions to go slow, but he never said it couldn't be vertical! After two loops, I had a sharp pain in my upper thigh. Apparently, the hip flexor or one of it's buddies took exception to my little Heartbreak Hill.
I need to get it through my head that while I may have some fitness right now, my running muscles have been on a beach with a fruity drink since the summer. I spoke to DW and he suggested an easy 30 min spin to keep it loose. That helped, as does staying in motion. Every time I sit still for a few minutes, it stiffens up.
I don't think it's serious but I might be living like a shark for a while. You know, move... or die. Still, I like sharks and I can think of worse animals to emulate.
