Decided to run in the park today for a change and to see what it's like as doing a race for life on Sunday ( will have to walk half of it). It was all going well till last 5 min run which ended up going up a small hill. Felt like a mountain! I slowed down but for to point I thought I would end up standing still. Got to the top though then there was only a min left to run. Legs and feet still tired 2 hours later. Glad it's a rest day tomorrow.
