Easy 5 miles

I have been bothered by right medial shin pain for the last two days. Is it soreness from a different pair of shoes on Thursday? Is it from the increase in mileage over the last two weeks? Maybe both. I am taking it easy this weekend and doing a lot of stretching. It is too close to the marathon to get hurt now. I'd rather be healthy and slightly undertrained.

Only five miles today. The shin pain got better after 3-4 miles, but was sore again after, just the right side.
