CTS - Dorset 2018
Extremely demanding and slippery course especially for the first 5 hours under constant heavy rain. I sadly didn’t get to see much of the Jurassic Coastline due to very low & (as mentioned above) rainy clouds. The last loop in the dark was really magical. Great support from public and organisers. The food at checkpoints was perfectly suited for my needs and the length of the race. 👍🏻

Fantastic route, depending on your distance. Staff are very friendly.
Endurance Life cater for 10k, Half, Marathon, Ultra and Ultra Plus, which is obviously a very difficult thing to do. The Marathon makes good use of the whole course without any repetition, but any of the longer distances require you to do laps of some sections, which I've never been a big fan of. There is very little food at checkpoints so you are required to carry your own.
Lots of water stops and access to your drop bag through the longer runs means you can re-fill your supplies along the way.
I like that this race caters for everyone and allows runners to grab ITRA/UTMB points before the ballot opens in mid December, but if you are looking to do anything beyond the Marathon without a need for the ITRA points I'd recommend finding a better course.

I did the Ultra+ (45 miles). The race was well organised and everything went smooth. The track was well signaled and I have never felt not safe! The locations was also pretty stunning.

Things that could improve are: the route was made by some sort of 3-4 loops. The food and drinks at the stations were not great (only water, bananas, biscuits and jellies). Having to chip in sort of manually was also annoying at times.

However, overall the race was pretty good and I can recommend it. Also, it's one of the few races that you can actually find in December in the UK, and in Europe!

I ran the Ultra (33.3 miles) in 2017. The weather was perfect when I did it, sometimes you can be lucky in December :-)
The event is very well organised, it is quite big as they are many distance options. The course is well sign posted, impossible to get lost. The aid station are pretty basic, so take your own food and electrolyte drink if you want to be on the safe side. The course is absolutely brutal! Up, down, up, down.... And the ups are super steep!
I gave 4 stars because, as others mentioned, having to go through the finish a couple of times because you can actually finish is not great.

This was my first ever ultra, ran the 33.5 miles - 53km run. Weather was great, start was good and the Marshalls were friendly and helpful. Course was pretty brutal, I expected the elevation and trained for it - although the gradient though was tough.
Really enjoyed the course and the great views, though aid stations were a little basic but other than that - all good.
Great experience for a first ultra.

My 3rd year in a row at this event. Beautiful scenery, brutal hills and luckily good weather this year! Ran the Ultra+ (45 miles) which meant two additional loops via the start/finish line which was unwelcome. The volunteers were all fantastic and would highly recommend. Only reason for 4* is they ran out of water at one of the checkpoints at the top of a long climb! Longer review on my blog

I did the 2017 (and 2016) ultra event (53Km) - this is a really excellent run with beautiful scenery. The weather this year was perfect - slightly cold but little wind and you could see for miles. The marshals and crowds were fantastic - really helpful and supportive. The course is really well signed and organised. Although this is billed as Intermediate be prepared for lots of hills and the 10Km loop at the end of the marathon is a mental test.
Would I do it again - yes.

Great race, beautiful scenery however it's pretty painful having to loop round the start again!

I ran this one in 2015 and conditions were pretty tough with steady winds of about 40 to 50mph and reports of gusts up to 80mph - it made for hard going and with the sustained uphills and exposed coastal trail made this a real test of endurance and mental strength!

I ran the Ultra (53k) and can make the following observations about the race:

1. The elevation profile and course GPX provided by the organiser was spot on.
2. The views are fantastic.
3. Having to run through the start twice during the race is a real test of mental strength!
4. Aid stations are very basic. If you require anything more than water and jelly babies then carry your own gear!
5. Marshalls and race staff are some of the friendliest I've come across in my years of racing. Really supportive.
6. There aren't too many places around Lulworth to carb load the night before or to eat the night after the race so book in advance.

Would I do this one again? Most definitely! Would I hope for lighter winds and clearer skies? Absolutely!

The Dorset CTS Dorset is one of only two events in the CTS series to be labelled 'extreme'. However, it's fair to say with it's consistent rolling hills along the Jurassic coast & up to 8000 ft of ascent, it could easily be ranked a 6.

Every other year I've done this event we have had stunning weather, but the 2015 edition broke that pattern and gave us howling winds reaching over 50mph, which literally knocked some runners off their feet! Nevertheless, the race went ahead, the marshalls were their usual friendly and good humoured selves, the views were stunning and the hills were both brutal and endless!

This is a great event for all distances, tough and beautiful in equaL measures. However, the longer distances (ultra, and ultra+) all pass through the start more than once and involve repeating certain sections, which can make for a real mental challenge. Worth it though!

You need to assume you will be essentially self-sufficient on these events, take your own food and any energy drink you may require as the aid stations are relatively minimal (although they always have enough water). The organisation is slick, and EnduranceLife manage to retain that friendly small-event feel despite being quite a large and established operation. All the events in the series are well worth doing, but Dorset is definitely the toughest. However, Lulworth also has the biggest selection of ciders we've ever seen, and some of the most impressive views!
