coming off base phase/when to up the pace.

[TheEd]

during the build up we try not to go too hard on the accelerator, so you could look at keeping the pulse below 165 bpm

however, it is meant to be a session where you able to run faster during the build-up, but not overtax oneself

hope this makes sense

ps.. will be interested to see what your pulse correlates to in pace
