About this race
The One To The Castle Windsor is a half marathon in Royal Berkshire, starting at Marlow Rugby Club at 9:30 am. The race uses river trail paths and links its route with landmarks around the Windsor area, with Windsor Castle as the name everyone notices first.
The castle gives the event its strongest piece of local identity: it is a royal residence about 25 miles west of central London, first built in the 11th century and used by monarchs since Henry I. Runners can also use the day for fundraising through GoFundMe, and the listed organizer is George Bottomley.
