Windsor Half Marathon

Windsor Great Park, Windsor, Berkshire

Organiser's Description

The UK's most picturesque half marathon! Windsor Great Park, the only Royal park managed by The Crown Estate, was once part of a vast Norman hunting forest which was enclosed in the late thirteenth century. The antiquity of the landscape is enhanced by the scattering of great ancient oaks for which the Great Park and its forest are renowned.

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 event also includes The Glynn Shefford Memorial Run, which is open to anyone over the age of 10, so if you fancy having a short run (or walk) over approximately 2.5 miles then this is the event for you. There will also be a 50m dash (approximately) for 5 – 9 year olds, which will cost 50 pence. Entries can be taken on the day in the Administration Marquee. Numbers will be given out on the day.

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. 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 you will forget quickly.

Glynn Shefford Memorial Run: 2 trophies will be awarded in each of the following young athletes age groups: U13 Boys & Girls; U15 Boys & Girls; U17 Boys & Girls. Age as at 31.08.19

All Half Marathon entrants will receive their race pack prior to the event. This includes the timing chip which attaches to the race number which will also be enclosed.

Whilst the official organisers do not recommend the use of headphones whilst racing, usage is permitted. Please be aware that entrants are expected to be able to hear safety marshalls and other races to ensure safety.


A well organise event

2018 was my first time running in the Windsor Half Marathon and I can honestly say it was a pleasant experience.
Great crowds, great volunteers helping around the route, start and finish is stunning and the bit in between is beautifully scenic. A little hilly in places. But that view when you turn down the long walk to the finish with Windsor Castle in your view I don’t think you can beat that. Liked the water bottles and targets for the bins. Loos didn't seem too overcrowded. Very well organised event and I'll do it again. Definitely.
