Running the Trail -- I aimed for 2 miles and did 3 which pushed me to the limit. This was/is a milestone! I alternated one minute walking with one minute running. My calves were sore that night (ice is my friend), but it didn't stop me from walking for 4 hours the next day. My ankle started to feel 3 days after the run - I had only done walking and cross training since then. My new friend - ice packs in "foot cooler" under the desk at work, ice packs at night. I like ice.
