I ran my 1st Around the Bay today. Now I only ran the last 15km as I did the relay with a friend. It was the last 1/2 that I did and it was crazy hilly. Although the 1st few hills weren't too bad, it was the last 2 hills that killed my achilles heals. Specifically the last hill, known as "Reaper's Hill". I ran up the hill. Ok, more like a jog but I didn't walk it. When I got up to the top and started running a little faster I could feel some kind of pull in my achilles heal on both legs. Not good. I had to slow down even though the last 3 km is a slight decline.
