In case you missed the history first time around, for 25 years between the years 1977 and 2001 it was THE off-road race to do, with runners coming from all over the country (and abroad) to complete this beautiful but challenging race. Foot and mouth caused its cancellation in 2002 and following this the race organisers were unable to get momentum back to re-start this popular race.

In 2015 we had the help of David Joyce, the original Race Director to get it re-launched, and we are delighted to say it didn’t put him off and he is back with us, we couldn’t do it without him.

Whilst it broadly follows the Offa’s Dyke Path, one of the quirks of this unique race is that to reduce the number of stiles runners must navigate, David has once again gained permission of every farmer/land owner to have the race go through their land and open their gates.

We hope the spirit of the event which was there every year from 77-01, will continue and you’ll look forward to this great race.

Offa’s Dyke 15 route

The route follows the road out of Hay, crosses open fields and tracks, climbs Betwys Dingle, then follows country lanes, climbing steadily, before a steep climb to the top of Dysgwilfa Hill, with panoramic views and an easy run down to Gladestry. The ultimate climb to the top of Hergest Ridge is amazing, and once at the top it's a glorious 4 mile run before dropping down quickly to the finish in Kington. Total climb 2,500ft over 14.5 miles.

    Tough hilly course with amazing views, muddy & slippery in parts so trail shoes needed. Very well organised event with great support from the marshals. Plenty of feed stations with water & jelly babies. Atmosphere at the end not the best I’ve experienced but a great medal made up for it. Would definitely recommend this race if you’re after a challenge 😀 .
  • Did the Half Marathon in 2019

    This was a beautiful race that was so well organised and marshalled. The only thing that would be nice is maybe something like Jaffa cakes or similar at the midpoint aid station!
  • Did the Half Marathon in 2019

    Great race, beautifully organised, friendly, and very enjoyable. Watch out for the hills and the views, both are stunning!
