The TP100 course follows the Thames Path for 99% of the race. The exceptions to this are listed below and are where our aid stations fall just slightly off of the marked TP trail. Whilst every one of these deviations will be carefully marked on race day, it is YOUR responsibility to take note of them and locate them. None of the deviations present anything more than mild and very short diversions off of the route.
It is strongly advised that you carry a map for the race. We recommend the Harvey Map as it is a concise and easy to use copy. These general maps do not display these deviations so making a note of them before race day is a worthwhile exercise.
The course is 100 miles in length. The total elevation gain is 1900 feet.
EVERYTHING BELOW WILL BE CLEARLY MARKED OVER RACE WEEKEND.
Mile 12, Walton on Thames/ Lower Halliford: The course follows the ALTERNATIVE Thames Path route, first crossing Walton Bridge and then meandering through through Lower Halliford & Shepperton as opposed to the southerly route which ends shortly afterwards at the ferry crossing.
Mile 67, Whitchurch Aid Station: Having crossed the bridge between Pangbourne and Whitchurch, runners will follow the Thames Path at first through the houses, before heading up Whitchurch High Street. Rather than continuing directly ahead, the course turns LEFT here, down Manor Road, around 300 metres before bending slightly left with the road. The aid station is in the village hall, a very short distance down the first right hand turn off of Manor Road.
Mile 85: Clifton Hampden Aid Station: The Thames Path emerges on to Clifton Hampden Bridge 85 miles in to the race. The Path then turns right to cross the bridge and makes a left to continue onwards on the right hand bank of the river. Instead of taking this left, runners, will turn right on to Clifton Hampden High Street, passing the school and church on the right and coming to a major traffic cross roads. Emerging at that crossing, runners will cross the busy Abingdon Road taking GREAT care and turn left to reach the aid station in the village hall. To get back on course runners will back track the way they have come before taking the right to continue up the right hand bank of the river.
