For anyone attempting their first 100 miler the Thames Path 100 is a great option. Well organised, well marked and well supported by the volunteers and staff that run the event. I'd highly reccommend running this race or any hosted by Centurion but I would also reccommend volunteering to see the reverse of what the runners are going through. I volunteered at this event the year before to get a feel for the race and it certainly helped knowing what was in store.

The 2015 edition was my first 100-miler and the 2017 edition my fifth, having completed all other Centurion 100-milers in the interim (SDW100, NDW100,A100). This is an ideal introduction to the 100 mile distance with undemanding route and terrain that is easy to recce and that never feels too isolated, even in middle of the night. Being a Centurion event, you are guaranteed top-notch organization, including well-marked route, full-stocked aid stations, and enthusiastic and knowledgeable volunteers. Being a fast route, the race is also well-suited for those seeking Spartathlon qualifying times, in addition to being a Western States qualifier.

This is my second 100 miler, the first was over a mountain so running the straight was completely different. The aid stations were really well stocked and the guys manning them were just awesome, very supportive and helpful. I got lost a couple of times, mostly because i was just enjoying the views and forgot to navigate the signage. Night time was slightly harder to see some of the route markings but this was probably more to fatigue then anything else. My ONLY complaint about this event would be that for all that effort the buckle has no year marking on it. So pretty pointless doing it again just to get the same one next time. Good race overall though !!

I entered TP100 as my first 100 miler following some recommendations, and they were not wrong. Navigation is not an issue. There are no hills to think about. The aid stations are well stocked. The volunteers were all super friendly and helpful. I had a great experience and wouldn't hesitate to recommend to anyone looking to step up to a 100 or aiming to set a good time on one.

Another excellent Centurion event (competed SDW 50 previously). Volunteers are very knowledgable and very helpful; it is nice to have someone 'look after' you at 3am when you are cold and exhausted. It was the first time that I have run through the night and I didn't expect the temperature to drop to zero (or close to zero). Would definitely come back for more. Steve

As always a great event put on by Centurion, well marked route and aid stations adorned with an ultra runners dream picnic!! Thanes path is pretty much completely flat apart from a couple of small bumps around 70 ish miles, dont underestimate the fconstant flat! Not as easy as it would seem, however, I finished in 2014 and 2015 and I get bored of running after an hour. great race and great atmosphere! Volunteers are amazing and cannot do enough for you.

A very well organised race. Well marked route with superb aid stations spaced regularly along the route. It's a flat course, which makes it sound easy, but in reality means it is relentless with no hills to break up the running. Easy to underestimate the difficulty and go out too fast.

I entered this race in 2015. It was my first 100-mile race and it was a great experience, despite the fact that I had to drop out due to injury at 95 miles! I didn't even get sick of the sight of the river, which surprised me. Some really pretty views along the way. Centurion organises amazing events and this was no exception. It may be flat but don't be fooled into thinking this is an easy 100-miler - there's no such thing!

Amazing event. The best possible organization and care from Centurion. Deceptively difficult being a flat 100. Do not underestimate.
