Overview

The setting for the Windsor Half Marathon is one of the most beautiful in the UK, the start and finish being on the Long Walk within Windsor Great Park and with Windsor Castle as the backdrop.

The course itself is all on road and quite challenging with plenty of hills spread around the route, but remember: what goes up must come down! All this coupled with beautiful scenery and traffic-free roads, makes for a wonderful experience.

The race takes place close to Windsor Castle within the confines of the Windsor Great Park. The course is two laps, one of approximately 4 miles, the other of about 7.5 miles with the remainder made up by the 1.5 mile Long Walk at the start and end of the race.

The course is best described as undulating. It has many flat stretches, but there are some hilly sections to make the race a bit more interesting. The final 1.5 miles Long Walk is particularly impressive. The impressive sight of Windsor Castle in the distance beyond the finish line is quite outstanding and not something many will forget quickly.

Cheers for organising an amazing event. First half for me, totally chuffed to sneak in under 2hrs. Only possible due to the incredible on course support and the amazing volunteers. See you next year! πŸ…πŸ» Richard Boyd

I was a few minutes off my target time, the first two KM’s were slow out of the blocks and then the hills played a part, but what a great race, I enjoyed it so much. Matt Telfer-Maleary

Massive shout out to the volunteers, cadets, medics, members of the public etc etc, so supportive all the way round. I will definitely be back in 2025. Emma Telfer-Maleary ❀️
