Runners will depart from Goring at 0900 on Saturday 14th October and make their way to Little Wittenham on the first out and back section on the Thames Path. On returning to Goring, runners will be faced with the more challenging but beautiful second spur of the course, out to Swyncombe Farm on the Ridgeway before returning to Goring a second time. Spur three takes runners west on the Ridgeway to Chain Hill before returning to Goring for the final leg on the Thames Path to Reading and return for their 100 mile finish.
The difficulty of this race should not be underestimated. During a dry spell the route is flat, fast and picturesque presenting ideal conditions for a trail 100. However, runners will also be faced with up to 13 hours of darkness and the possibility of low temperatures and wet and windy conditions. Conditions underfoot can vary dramatically.
As with all Centurion events, runners will be fully supported by 16 well stocked aid stations , full medical support and course markings in addition to the pre-existing National Trail waymarkers. Race held under full UK Athletics Permit granted through the TRA (Permit Number 5399).

The course is marked by national trail marker posts which come in different forms but most commonly display the acorn which is the key symbol and guide on both the Thames Path and the Ridgeway.
In addition to the National Trail markers, the course will also be marked with Centurion branded reflective ribbons and marker arrows. There are a number of road crossings to negotiate, some of them are extremely busy. The road crossings are NOT marshalled. Please be extremely careful when you are crossing roads of any nature.
It is ultimately the runners responsibility to navigate the course successfully, with or without course markings. If you are in any doubt we strongly recommend that you take the time to recce the route before race day.
Pacers are permitted from Mile 75 (Leg Four only). Pacers may join a runner only at Mile 75 and must cover the entire of the 25 miles (Leg Four) with their runner. Pacer handovers are not permitted anywhere other than HQ at Goring.
Crews are not permitted at this race due to the size of the aid station locations and pressure on the local community. This rule has been in place since 2017.
There will be a dedicated team of race medics available throughout the duration of the weekend. If you suffer an injury or accident that warrants direct medical attention, the medics will be on hand to provide you with exactly that. Contact numbers and full details of what to do in an emergency are available in the information packs and will be re-iterated in pre-race mail outs and at race registration. Due to the nature of the course ie. some off road, the medics may take some time to reach you, or potentially be out of contact tending to other runners. A level of self sufficiency is absolutely critical in such situations.
The majority of the course is on trail. Trail shoes are advised especially given the time of year. There are sections of trail which can become very muddy or flooded in wet conditions.
There will be random kit checks prior, during and after the race. Runners must carry the following mandatory equipment at all times. A time penalty of one hour will be imposed for any item found to be missing at any point on course. Please refer to this page for explanations on the inclusion of the below items.
There are many options regards kit for fulfilling these requirements and those of other events. We stock what we believe to be the best options at our online store available by clicking here under the Mandatory Gear Section. Please ask us if you have any questions.
