Good to see we are getting a reputation on here for going that extra mile to get the training in 
I have been toying with the idea of getting up at silly o'clock to go and do my tempo session but have decided against it. If it freezes overnight the route I do will be treacherous and the other options would not be great.
I am going to gamble on it being ok tomorrow evening to go for it. I really want to see if I can both increase the length of the speed section and also squeeze a little out of the time (my target will be 7:15 mm or better over 25 / 30 minutes).
If my gps is still playing up I can always use the stopwatch for this section and I will be able to work out my time. Must see what deals are out there on the garmin.
If not I will have to go to the gym.
Spoons - how best to approach a tempo session on a treadmill ?
