 The Summer Trail Series by Asics takes place on the hills and dales of “God’s Own County”, Yorkshire. Located in West Yorkshire, Calderdale is the southernmost of the Yorkshire Dales and covers part of the South Pennines, an area of beautiful river valleys, moorlands, and hills.

The Summer Trail Series by Asics offers three race distances: 75km, 50km and 25km.

As is always the case with Ultra X events, these are far more than just races, they are awesome experiences. At the start/finish there will be an expo selling merchandise, hot drinks, food and much more. You are actively encouraged to stay on after your race and enjoy the festivities, BBQ and bar.

The address for the start/finish is the same for all three race distances: Mytholmroyd Community & Leisure Centre (HX7 5AF) or what3words location verse.greet.riches.

The start is a 5 minute walk from Mytholmroyd train station and there is also parking readily available at the Community & Leisure Centre, which can be booked on registration. There is limited parking in Mytholmroyd town centre.

All races are held under full UK Athletics permit granted through the TRA.
