The course is marked by permanent national trail marker posts maintained by the National Trails Trust which come in different forms but most commonly display the acorn which is the key symbol and guide on the Thames Path.
In addition to the fixed markers as above, the course will also be marked with reflective red, white and silver tape and Centurion marker arrows. Some temporary orange chalk paint will also be visible on the ground at major junctions.
It is always possible that course markers may be removed or vandalised, in which case runners may well need to use the National Trail marker posts and maps as the guide. There are a number of road crossings to negotiate, some of them are extremely busy. The road crossings will NOT be marshalled so 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. We strongly recommend that you take the time to recce the route before race day & carrying a map and compass are highly recommended for the event in case of an emergency. The Harveys Thames Path map available at a discounted rate here, is an excellent guide.
100 mile runners are permitted pacers from the 51 mile aid station at Henley. Pacers must travel on foot only. Runners are permitted multiple pacers throughout the last 49 miles but only one may travel with the runner at any one time.
The points at which a runner may be paced/ hand over pacers are listed on the crew page here.

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 will be given to you in the pre race information packs and again 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. In those instances you should contact the emergency services on 999. If you are injured but able to walk, please make your way to the nearest aid station where there will either be a medic, or an aid station captain will immediately get in touch with medical care should you require it/ arrange for transport out. If you suffer a severe injury or encounter someone in serious difficulty please call both 999 for emergency ambulance services and the course medics.
