Thames Path 100^®

What date is the next event and when do registrations open? 

The 2021 event will take place over the 8th-9th May 2021.

How tough is the course? 

With 1900 feet of total gain over the full 100 miles, major elevation change is removed as an obstacle. The only significant ascents are between Whitchurch and Streatley (short trail climb) and short ramps or flights of stairs used to cross bridges from one side of the river to the other, but these are few and far between and it is rare that they are longer than 20 to 30 steps. The flat nature of the course also presents it's own challenges with many runners unused to such a minimal amount of elevation change and the repetition thus required.

In terms of terrain, roughly 75% of each course is on trail and around 25% on sections where the Thames Path has been paved or exists as tarmac road. If it is wet in the lead up to the race or on race weekend itself, some sections will become muddy and require due care and attention. Expect a mixture of road, pavement, hard packed mud and soft mud if it is wet. It is always possible that the river may be in flood in which case the situation will be monitored closely in the lead up to the race and necessary course changes communicated to competitors.

Weather in May in the UK can be changeable and runners must carry the mandatory items/ be prepared for the conditions to be very hot, or be very poor or deteriorate quickly.

It gets very cold alongside the river at night.

What do I get for my entry fee?

Is there a minimum qualification standard to achieve before I can enter?

How do I update my qualifying information?

Once registered, you may update your qualification information by heading back through your confirmation email or logging on to racedirector.com via this link.

Will there be live updates during the race for friends and family to follow? 

Live tracking is available for all runners at every stage of the race. A link will appear on the home page just prior to race day.

Are there any road crossings or gates/ stiles to negotiate? 

Absolutely yes. Whilst the Thames Path is predominantly trail, some of it is on road. There are sections of the course where you will be running along and across both single and double lane carriage ways. The majority of these are very quiet country roads, however the trail does appear at busy road junctions, at some points abruptly and therefore you must be alert at all times. Runners pass along the course entirely at their own risk. Much of the Thames Path is on private land and as a result there are gates and stiles to negotiate throughout the length of the course. All gates must be closed properly after you make your way through. 

Is there mandatory gear to carry on race day?

Runners must carry the following mandatory equipment at all times. There will be kit checks prior during and after the race. A time penalty of one hour will be imposed for any item found to be missing at any point on course
