Fly the nest from St Aidan's to Fairburn Ings!

Just like the St Aidan’s 10K , but more so! This is the trail half marathon that takes you round  not one but two nature reserves!

Following on from the success of the St Aidan’s 10K (formerly known as the East Leeds 10K), we now bring you a trail half marathon that starts (and finishes) at St Aidan's RSPB nature reserve but also takes in Fairburn Ings RSPB nature reserve.

The course starts close to the RSPB visitor centre at St Aidan's Nature Reserve and follows the River Aire for a spin around Fairburn Ings before returning back to St Aidan's.

Starting by the Visitor Centre, after a quick loop of St Aidan's, the route follows the River Aire to Fairburn Ings, does a loop of this second nature reserve and then returns back to the start.

Is it chip-timed?


What will I get?

Definitely a medal and something wearable (it was a beanie in 2018).


And our prize sponsors for 2019 are T8; ultralight, supercool, chafe-free running gear designed by Ultrarunners.

St Aidan's Nature Reserve

Just a stone’s throw from the centre of Leeds, St Aidan’s nature park is a stunning wild place to explore. Whether you’re on foot, on your bike or have your camera at the ready, take advantage of the amazing views and wonderful wildlife spectacles on offer.

St Aidan’s was an opencast mine for many years and has now been restored to a wonderful nature park for everyone to enjoy. Follow four different trails through woodland glades, alongside whispering reedbeds, around lakes and ponds, and onto a hill with stunning panoramic views.

St Aidan’s is a fabulous spot to bring the family. There’s plenty of space to explore, bring your bikes and run around. It’s early days for St Aidan’s. We’re just setting out on our journey. We’d love to share it with you.

Fairburn Ings Nature Reserve

Nestled between Leeds, York and Wakefield, Fairburn Ings is an exciting site for family activities and serious wildlife watching. Over the last 60 years it has transitioned from coal face to wild place; an ex-industrial site rich in heritage and an important site for breeding and wintering wildfowl, especially gadwalls.

30% of net profits from this race shall be donated to the RSPB. This is expected to be at least £700. RSPB is a registered charity in England and Wales, number 207076, and in Scotland, number SC037654.
