LM warmup. First run was 3.36 mi, 8:19/mi, HR 146 w/ 6 x 1 min repeats. Trip to the chiropractor. 2nd run was 5.14 mi, 7:51/mi, HR 159 x/ 12 x 1 min repeats. Stretching afterwards. Tightness came on again at about 1/2 mile. Left leg felt like it had no power, couldn't stride out, body tried pulling to the left. Tried to do some repeats and they went okay, but form still didn't feel right, and about 1.5 miles in, I decided to hurry back home and see if I couldn't get down to see the chiro. Short version is that my left hip was rotated forward pretty significantly, so I couldn't really stride correctly, tensing muscles that should've been relaxing, etc, etc. Back home and attempted to finish the workout. Much, much better, stride was back, virtually no muscle tension issues, and my left leg had power again. The left hip felt a bit more tired as the workout progressed, but since I've been suffering with this for a while now, I'd suspect the muscles need time to readjust and strengthen, and another trip or two to the chiro will be needed. But the good news is that I believe I found the problem and can now fix it. Thank heavens for chiropractors that know what they're doing! |
