Half Marathon River Trail Run - 13.1 miles - Remember this is a trail run, so nature at its best


The Royal Windsor Half Marathon River Trail Run Trail Run creates the perfect opportunity to experience the historically picturesque Thames Valley.

With an idyllic start and finish at the foot of Windsor Castle, a royal home and fortress for over 900 years, the entirely flat river route guides you upstream to Maidenhead before heading back towards Windsor.

Mainly run along river trail paths, the course incorporates many of the key landmarks that have made Royal Berkshire and its surrounding area so famous. It is an absolute must for anyone looking for a break from the pavement grind and a change of scenery. The course follows natures trails and as a trail run the course although measured will never be 100% accurate.

With a huge increase in demand and listening to participants feedback, we have limited the entries to 1500 participants in 2017. This is now an annual event and a great way to start your summer, and enjoy the best of Windsor, Boveney Lock, Bray, Dorney, Maidenhead and Eton.

The event is not designed to be a gruelling cross country through deep mud and puddles, but aims to be a fun, friendly and fast trail run along one of England’s most historic courses.  We hope that our onsite facilities, commentary and music provide plenty to keep other halves and little ones entertained, ensuring a day out for all the family while you run.

Our waved-start format creates a relaxed and friendly atmosphere, limiting any participant congestion along the route.  The course is accurately measured using latest GPS tools and electronic chip timing is provided, so finishing times can be used for future event entry.

The official cut off time to complete the Half Marathon event is 3 hours 30 minutes, making the event achievable, even if you decide to mix walking with jogging along the course.

There is a minimum participant age of 16 for this event. For participant health and safety, we also ask that there are no prams or dogs taken out on the course.
