This is the first ever Royal Windsor Trail Run Half Marathon and has been a year in the planning. If you have never visited the Thames Valley or Windsor & Eton, this could be the perfect opportunity. Take part in this inaugural Half Marathon that starts and finishes at the foot of the largest living Castle in the World – Royal Windsor Castle. If you have time on your run, jog, walk to keep looking around, you will be taken through a guided tour of some of the best landmarks that have made Royal Berkshire and surrounding area so famous. The waved-start format creates a relaxed atmosphere, and the facilities ensure a full day out for the family, with plenty to keep other-halves and little-ones entertained while you run. The Official cut of time is 3 hours 30 minutes to complete the course and is achievable if you still decide to walk/ jog the course.
