Quite a step up from week 3. I was fine for stamina on the first two sessions because I chose to run in the local park which is pretty flat. However on Wednesday it was so muddy that I slipped and badly grazed the knuckles on my right hand. There was blood and mud everywhere. On the following run I decided to run along the canal towpath to avoid the mud, but I'm afraid this involved climbing for some 9 locks on the way out. Why is it so hard going up hill?
Now to see what week 5 has in store.
