Errr........ it depends on what you are physiologically (genetically) capable of! Training helps obviously but there are limits. For example if I did the same training as my boyfriend we are going to end up doing very very different times. Are you an 'average' athlete, slightly better than average or slightly worse? Where do you normally come in your local MTB funrides? I put together a short spreadsheet for K2C based on the published profile and estimated what I thought I should be aiming at. e.g. I generally go uphills of x% at a certain speed, so I would enter that speed to estimate how long it would take me to do a particular section, etc etc. Twas a good guess in the end
