Today was the best day in over two weeks. I ran 10k and I'd say my tendon is back to 75% or more, so things are looking up but I'm still going to take it somewhat easy. I'll probably take tomorrow and maybe Sunday off and then try to get back to daily running on Monday. There are only 3 weeks left until the marathon, so there's not much I can do to improve my conditioning. The key for me now is to stay injury-free, have fun during the race, and finish it :-).
Total:
10k (6.2mi) Run
