adidas TERREX Trail Half Marathon


Saturday 21st May | 11:00am

The 25km Trail Half Marathon (and a bit!) is graded ‘Hard’ and sits almost halfway between the 10km & 50km routes in difficulty, ascent & terrain you run on. Technical, fast flowing and rugged trails take you around Derwentwater and the Borrowdale Valley with the Watendlath Valley thrown in for good measure.

If you’re looking for more than our 10km trail run but not quite up for the 50km Ultra Marathon, then try this 25KM option which is just slightly over the half marathon distance. Ascent: 866m It will test you to your limit or get you set for longer trails later in the season. If you’d like some help with your training, check out our free half marathon training guide in the tabs below.

Choose the most appropriate wave:

Elite/Fast – Sub 3.10

Leisurely | Leisurely/Cruising – + 3.10

Leisurely – +4.00
