And I was only supposed to do 3!!! Shins started playing up after 5 minutes, and escalated until around 15 minutes (when it became intermittent).

Reached 30 mins, then kept attempting an extra minute, then another, and so on till I was at 5 miles.

Now I'm too tired to even type this (my lovely wife is playing secretary, hence all the exclamation marks!!!)

Will try 3 miles tomorrow, then attempt 5.5 on Sunday - another personal best (distance-wise) if I can achieve it.

Will need at least 2 bottles of Lucozade (other sports drinks are available) and a much much cooler gym.
