So with that in mind I decided to train for hills and with a training manual and some advice from a “so called” expert I set out and sprinted up a short hill (0.25 mile x 4%) by me for 40 seconds (nearly threw up) rested 30 seconds and carried on like this for 6 reps, result, from the second one on my speed was so slow through not recovering enough, that it was worthless.

Now this article by Tejvan makes far more sense and pleasanter to do (if that makes sense) as I found it takes even more guts to take yourself to your limit.
