The Harwell Half Marathon will not be happening as planned on Monday 28 August due to significantly low entry numbers 9 days prior to the event making the event unforuntanetly un-financially viable.

We are as sad as you to cancel this event as it really is stunning, but unfortunately we have costs to cover and commit to prior to the event and cannot afford to run this event at a loss.

Why not check out our RARE 5km/10km at the same venue on Sunday 8 October 2017 instead.

Thanks for understanding

“I have done many half marathons over the years and this is definitely my favourite one!!! 
It ticks all the boxes. I couldn’t fault it, the marshals were super, it was well organised, a beautiful route and so, so friendly. The directions and parking were perfect too.”

It’s back again due to popular demand…..


13.1 miles — 10am

The route starts off flat and then gently undulates along footpaths, bridleways, and tracks up onto the Ridgeway National Path from where you can enjoy some stunning views of the rolling Oxfordshire countryside.

Altogether a better way to spend a Bank Holiday Monday!
