Course Markings

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. 


Crew/ Pacers for 2020 only - runners are limited to a maximum of 2 crew people and/or 2 vehicles at any one time on course. Eg. Runner may have two members from their household/ bubble in one vehicle, or two separate crew people each driving one vehicle each. The points at which a runner may be crewed are listed on the crew page here. Crews/ Pacers/ Supporters are not be permitted meet their runner at any point other than those listed.


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. If you come across a fallen runner please remain with them until help arrives.

For 2020, the medical team will operate a “Non” Standby at Aid Stations policy, but will attend when called in.  Ambulance Crews will be attending every incident in a minimum of Level 2 PPE (Gloves, Mask, Apron, Eye Protection) and reserves the right to pull anyone suspected of exhibiting Covid-19 Symptoms from the race with immediate effect. Where a runner, volunteer or crew exhibits COVID-19 Symptoms on race day, they are to be isolated from all other participants.  They will then need to be returned to “Home” to self isolate and arrange a swab test.   We may need to consider this for people who have used public transport to get to the event (they won’t be able to use public transport to return home). Those who have driven themselves to the event can be returned to their car by the Ambulance and given instructions to return home immediately for isolation. Those who have taken public transport will need to find another way to get home (I assume this is their responsibility).


75% of the course is on trail. Trail shoes are advised but if it's dry, you will be able to complete the course perfectly adequately in road shoes which have good grip. There are sections of trail which can become very muddy in wet conditions. The weather in April is extremely variable and can include anything from snow to heavy rain or bright sunshine. Be prepared for all conditions. 

There will be 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.
