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

The 6th edition of the Thames Path 100 will take place on Saturday 29th April - Sunday 30th April 2017. Registrations will open on Saturday July 23rd 2016 at 1000.

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 April  in the UK can be changeable and runners must carry the mandatory items/ be prepared for the conditions to be poor or deteriorate quickly.

It gets very cold alongside the river at night. Temperatures in 2016 hit 0 degrees C at 3am.

What do I get for my entry fee? 

Principally you get a fully supported race including:
14 fully stocked aid stations including hot food and drinks at multiple points
A marked course
Full Medical Support in the form of dedicated race ambulances and roving vehicles as well as static first aid teams

Is there a limit to the number of entries into each distance/ Can I enter on race day?

General Entries are limited to the first 300 applicants. There will be a waiting list in operation once the limit has been reached. An additional 60 places exist for the 2016 Volunteers.

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

In order to enter you must have completed a minimum of a 50 mile distance race within 15hrs, between 1st January 2014 and race day. As organisers, we reserve the right to refuse anybody entry who does not meet this standard. Unqualified runners may enter but will be contacted approximately 8 weeks prior to race to verify qualification plans if they have not updated their online information by this time.

How do I update my qualifying information?

Once registered, you may update your qualification information by heading to this link (link to follow).

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

There will be a live webcast during the event. Live times will be published as runners come through the major aid stations. Twitter updates will also be going out across the weekend. A link to the live site will appear on the homepage in the week leading up to the race. 

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. 

A list of all of the major road crossing on route can be found here. 

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

Are crews allowed?

Yes. If you want to have your crew, friends or family meet you you may have them do so but only at the points listed on the crew page here

Our race permits and the future of the race depend on our positive interaction with the environment and communities through which we run.  Any runner found to have crew violating this will be subject to the rule violation procedure.

NOTE: Please also ask your supporters to meet you only at the designated crew locations. The reason for restricting access to certain points, is predominantly parking and noise limitations, hence supporting is as much of an issue in sensitive areas as crewing.

Do I need a different drop bag for each aid station?

Yes. Runners need to leave a different drop bag for both Henley and Streatley, each bag will be transported to the aid station listed and then to the finish line only. The exception to this is the finish line bag. Each runner may have one bag to be taken directly to the finish line for them.

How big can my drop bags be?

Maximum size is 30cm x 20cm x 20cm or the size of a shoe box/ small backpack/ drawstring bag. Your finish line bag can be bigger than this.

Drop bags will be accessible at the following points and will be available for collection between 10am and 2pm at the finish line. Runners need to leave a different drop bag for each aid station, each bag will be transported to the aid station listed and then the finish. Finish line bags will be taken directly to the finish only.

What happens if I need to drop out?

If you need to drop out of the race, it is your responsibility to get back to where you need to get to but we will endeavor to help you as much as we can. If you have to drop please do so only at an aid station. Please inform the aid station captain on arrival that you intend to drop and whether you need assistance. If you need to drop out away from an aid station for medical reasons you must phone the race director immediately on the number provided at check in. If you drop at an aid station, the Aid Station Captains will inform you what time the shuttle bus will come through. You may have to wait some considerable time so please be patient with the volunteers. If it is imperative that you get away immediately you will be given other options involving local transport services.

All aid stations will have a full selection of the usual aid station fare and a whole lot more.

Hot drinks will be available at all aid stations from Hurley onwards.

What level of medical support can I expect?

Medical support is of paramount importance to us as organisers. Throughout the event there will be two ambulances on course, which will travel, one with the main group of runners and a second towards the back of the pack. There will also be a fixed medical team on hand at the finish line. Individual first aiders/ medical volunteers will also be present at some aid stations. Contact numbers for the medical team will be available at registration. They will be contactable round the clock for the duration of the race.

I need to withdraw, what is the refund/ transfer policy?

Withdrawals after that time will not be refunded for any reason as all race day costs have been incurred by that stage and you will not be replaced.
