Loved by Bristolians and beyond, the AJ Bell Great Bristol Run is known as the best in the South West – and for good reason.

Each year, thousands of runners push their perseverance and passion to the limit and take on Bristol’s super-scenic 10K and half marathon routes. If stunning views, inspiring history and graffiti murals are your thing, then the Great Bristol Run is right up your street.

Bristol, I love you so much and Great Run what a fantastic experience you gave me for my very first race, I will be back!

Very well organised event, Great Run do a fantastic job. Nice medal and goodie bag, well-supported route. It's a staple in the run calendar.

A great experience that must be tried by anyone who likes to run! Fast and flat, it's ideal for achieving that PB! Great views of the city.

I'd definitely recommend this race to anyone looking to do a 10K race and get the feel for a 'big' running event.

Loved everything about it, the support, course, medal. One of my favourite runs.

A fantastic event that I will never forget. Can't wait for next year.

I truly believe it's all about believing in yourself. My only regret is I didn't do this event years ago.
