The Dark Downs Half Marathon is a beautiful route in a stunning location, through the South Downs National Park. It is an achievable single loop trail race that is a great option for first time trail runners and, also a great way to prepare for longer events later in the year.
There is something quite unique about running at night. The atmosphere, the camaraderie, the challenge, the novelty, and the cooler temperatures all make for a fantastic experience and this race will hopefully provide all of this. The South Downs as always will bring rolling hills, runnable trails, and are also ideal for a race in the dark due to its untechnical terrain.
Permit: Our permits are granted through ARC. Permit pending
The South Downs were awarded the Dark Sky Reserve Award in 2016 due to its exceptional starry nights, so there is no better place for a race like this to get some amazing views. The race will start at 6.15pm on Saturday, September 27th 2025, as the sun is setting, and runners/walkers will have 4 hours to complete it.
Entries are available on a first come, first served basis and once it is full, they will be closed. No waitlist will be in operation. No qualifier is needed in order to participate. Entries will close 1 week prior to the race or once entry limits are reached.
Anytime until July 30th you are entitled to a 70% refund. After this no refunds will be given. The only exception to this is pregnancy in which case you will be entitled to full refund at any time. If you can no longer make the event, there is the option of deferring your place to 2026 or transferring it to another runner. This can only be done up until 1 week before race day and, not after. Pregnant women will be able to defer their place until 2027. Please email neil@ukultra.co.uk if you wish to do either of these.
