Thames Path Ultra Challenge.
The 25 km is the shortest way into the Thames Path Ultra Challenge: from Putney Bridge up the Thames Towpath with next to no gradient. Walking, jogging and running are all part of the event, so your preparation starts with a decision about which of the three your day is going to be.
Thames Path Ultra Challenge 2027: Course, Route Profile & Map
The start is at Putney Bridge, and from there you follow the Thames Towpath upstream. For you this is only the first piece of the route to Henley: the 25 km is the opening of the line the longer distances carry on along, and as a point-to-point course it does not bring you back to Putney.
Climbing hardly enters into it. The path stays between four and ten metres above sea level, and the total of around 50 metres is made up of small change. That means there is no spot where the gradient sets your pace for you, and none where the course makes a decision on your behalf. The rhythm is yours from the first kilometre to the last.
More than 3,000 people take part in the event, and walkers, joggers and runners share the same towpath. The route is signed and covered by GPS tracking, with rest stops roughly every 12.5 km. In practice that gives you one stop with food and drink around halfway, with medical support on hand. This is not an ultra; it is closer to a look at what everyone else has ahead of them that weekend.
| Start | Length | Ø | Max. | Gain | Cat. |
|---|
Climb categories follow the road-cycling convention and rate the terrain itself (length and gradient) regardless of sport: Cat. 4 marks the easiest rated climbs, Cat. 1 the hardest, and HC (hors catégorie, “beyond categorization”) is reserved for the most brutal ascents. Short climbs below the Cat. 4 threshold stay unrated.
How to pace Thames Path Ultra Challenge.
Start under control
If you are running, this is a pure tempo course: nothing climbs, so your breathing alone tells you what is possible. Divide it as an even steady run, with a first half that feels almost too easy, and only ask whether to push on after the halfway rest stop. If you are walking, pick a stride that lasts five hours, not one that looks good in the first kilometre.
Hold your rhythm
The trap is confusing flat with easy. Starting a little too fast costs nothing at first on the towpath, because no gradient warns you. The bill arrives after about 18 km, and by then no change of terrain is going to work your muscles differently and give them relief.
Spend what is left
That is also where your result is settled. The last seven kilometres ask for the same movement as the first, except that now it takes concentration. Keep the stride short and the cadence up rather than trying to rescue the pace with force.
Training plan for Thames Path Ultra Challenge: 12-week build
Build the base
Runners will be out for about 2:15 to 3:30 hours depending on form, walkers more like five to six. Either way this is an even aerobic effort without spikes, because the course produces none: no climb pushes your heart rate up, no descent gives anything back.
Train race pace
The decisive phase is the closing stretch, once the same repeated movement has tired your hip flexors and calves. So your long run should grow to 18 to 22 km over the final weeks, with the last kilometres at planned race pace. Walkers build the same logic with walks of up to around 20 km.
Rehearse the course
If you are running for time, one weekly session of longer blocks just above race pace is worthwhile, done on the levelest path you can find. The course does not ask for climbing strength; it asks you to hold a pace for a long time with no help from the terrain. Hill intervals are wasted energy here. Strength work for hips and calves is a better use of the time, since those are the muscles that work without a break on the flat.
Arrive fresh
The mid-September date puts your build-up in summer: ten weeks out is early July. Use that time to practise eating and drinking briefly after about 12 km and dropping straight back into rhythm, because that one stop is the only one your race has.
