I am in a state of shock!
I went on the usual dog walk. I've been doing it every day (apart from when Millie had her poorly foot) along the canal. One mile to the wharf and then back again. Its been taking me around 30 minutes at a very brisk walk.
Today I decided to run! Only small, short bursts of running but I managed 6 lots of running in the two miles.
And I felt fab!
I still did it in the same amount of time as my walk slowed slightly between runs.
