Event overview

Trails & Tarmac Backyard Ultra - Winter is a backyard ultra event held in Crickhowell, Powys, set in the Black Mountains. The route is roughly 50% trail and 50% tarmac with one gradual climb, a short steep section, and otherwise relatively flat terrain. The course uses a loop of about 4.2 miles. Medals are awarded to any competitor who reaches 32 miles (ultra distance). The last person to complete a loop is allocated the winner's trophy; other runners who finish before 32 miles are recorded as DNF in that context.

Format and rules

The event uses repeating hourly loops. Each loop must be completed within one hour to count. Competitors must start each loop at the bell; countdowns are given before each start. Runners may not leave the course during a loop except for restrooms. Personal aid is not allowed during a loop; a common aid station will be available at the event HQ. No non-competitors are allowed on the course, and no artificial aids such as trekking poles are permitted. Timing is provided and results report distance covered. The event is open-ended.

Facilities and entry

Event facilities include medics on site, showers and toilets, event photographers, and a GPX file for the route. Basic camping is available in a nearby field with toilets; other local camping and recovery services are listed by the organiser. Parking at HQ carries a fee and includes entry into a ballot for a free event. Entry fee is £100; minimum age is 17. Visit the organization's website for the most recent information.
