Othnesbery’s Revenge Half Marathon MMXXVI

Now in it's 5th year.

"I've  never thought of going up and down Roseberry Topping three times but I absolutely loved it"

Have a look at our website www.SilverBackTrails.com or SilverBackTrails FB page for photos and drone footage, along with a  full length video of the route from Chin Yong , who was last years first finisher.

Registration is from 08:00 am  start at 08:45.

A trail half marathon, circa 13.1 miles over the beautiful North York Moors National Park.

4.5  hrs cut off. 

The route will take you through forest tracks over heather-clad moorland, which in August should be a stunning purple colour, and up one of the most recognisable hills in the country, on early mapping it was even classed as a mountain...

Othnesbery, more usually known as Roseberry Topping has been linked to Odin chief of the Norse Gods, it would have been well known to the Vikings who lived throughout the area during the time of the Danelaw. Can you dig deep and conquer Othnesbery’s Revenge where a sting in the tail will await you at Odins Seat?

Places are limited to 50 lucky runners.

 All finishers will receive a bespoke medal especially commissioned for the event and a certificate of their achievement which will feature a prominent  part of the route.

No bells, whistles or gimmicks, just a great route with a sting in the trail! 

A short video, pictures and comments from a previous year  can be found on our SilverBackTrails FB page and our website at www.silverbacktrails.com
