I have rested yesterday and today (I consider any day that I don't run a "rest day" even if I do 1000 pushups). So I am taking it easy even today. No pushups, no easy runs. Just working and eating lightly and hydrating. My weight loss has hit a plateau and my legs are much better. I think I will do some 5K tempo runs tomorrow, clear week 5 of 100 push ups on Saturday and go for 20K run on Sunday. Next week I will take it easy (I hope I will have the discipline and no injury) so that I can do 23K on 14th September. I think I can achieve my sub 1:40 half marathon time.
