The TMBT 2017 courses are largely finalized and are similar to the 2016 courses with only minor modifications. The distances and elevation gains are expected to remain largely the same for any further optimisation, and the ITRA points will be maintained.

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.
