Hard 10 miles tonight. Not in terms of pace, but of difficulty. Started with stomach cramps that necessitated a short break, then legs refused to loosen for about 7 miles. Finally started feeling better after I accelerated at the midway point to 8:20 pace, then finished with the last .5 at GMP. Left foot didn't feel very good, either, which is a little worrisome; any twinge makes be start thinking stress fracture. Hopefully its just another twinge that will be gone in the morning. |
