The TMBT 2017 courses are finalized and are similar to the 2016 courses with only minor modifications. The distances and elevation gains remain largely unchanged, and the ITRA points will be maintained.

A couple of changes have been necessitated by recent extreme rainfall and associated floods and landslides that took down a hanging bridge and made part of the 100 km course impassable. The rerouting for the 100 km will involve a short shuttle with the clock stopped to avoid the dangers along a main road section. This is described further in the logistics update found in the TMBT dropbox.

Course profiles and course data is included below. Please note that the cut-off times have been slightly extended for the 100 km and 50 km course to allow the slower but persistent competitors to complete the courses within the set cut-off times.
