Welcome to the UK Ultra South Downs 100 miles

The South Downs 100 miles, is a point to point, trail race through the beautiful South Downs National Park. Runners will begin at the stunning location of Queen Elizabeth Country Park in Petersfield, before travelling along the picturesque Staunton Way, Monarchs Way and South Downs Way before finishing over the iconic Beachy Head cliffs of Eastbourne. It is a truly epic route with lots of flat running in the first half before hitting the hillier sections in the second. It has a real mixture of terrains to keep it interesting and some really, stunning scenery throughout.

Permit: Our permits are granted through the ARC. Permit Number pending.

Entry & Qualification details:

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. In order to qualify, runners must have completed at least a 50 mile race within the last 3 years. Ideally this should be a trail race but it is not mandatory. Runners must also have a good amount of trail running experience in general, and of running during darkness. Runners can enter before achieving this qualifier but it must be updated before race day. To update this please email neil@ukultra.co.uk Entries will close 1 week prior to the race or once entry limits are reached.

A qualifier can come in many forms but essentially you must have run 50 miles or more in a race format where results can be viewed. Any road or trail race is fine as is a double Ironman. Please get in touch via the above email with any queries regarding what counts as a qualifier.

Anytime until March 22nd 2025 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 2026/27. Please email neil@ukultra.co.uk if you wish to do either of these.
