What are the cut off times?
Nearly all participants finish the race and only through multiple flat tyres or other unforeseen issues will a rider or runner need to pull out.  Purely for safety, the EXTREME DAY 1 cut off is 4.00pm, CLASSIC DAY 2 is 12noon at the split point and  CHASE DAY 2 is 8.30am at the split point. Most participants reach this point well before the cut off but if you don’t make it in time, you will simply be directed onto the shorter route or picked up by the sweeper car.


Race routes and topography maps can be found on the website here.If you would like KMZ files, please email: This email address is being protected from spambots. You need JavaScript enabled to view it. .
