PHOENIX Running is inviting you to join us for one of our Jubilee River Runs at our lovely Jubilee River route - the area is just stunning. The route is flat and wide, as you leave the Riverside Centre with Slough behind you, you enter the countryside and follow the crushed stone path with the river Jubilee on one side and fields to the other, on reaching Dorney wetlands you turn back enjoying views towards Windsor Castle. This is one of our 6 hour timed events where you choose - you can complete as many, or as few, laps as you like of a 5.24 mile, out and back, course along the beautiful Jubilee river. We welcome all abilities of runner - complete one lap and you're both a finisher and a winner in our eyes, or keep going and see how far you can get in the full 6 hour time limit and everyone gets the fabulous bespoke finishers' medal. Not sure? Well the beauty of this format is that you don't even need to decide in advance - simply come and run a lap and see how you feel on the day and keep on going if it feels right. Places will be strictly limited so don't leave it too late to enter. Minimum distance is 5.24 miles or as far as you can go in 6 hours. Off road trail, the terrain is riverside towpath. The overall course has no elevation gain / loss making this a flat and fast route.

The Phoenix Minotaur 50 Mile, Hydra 75 Mile and Centaur 100 Mile Ultra Marathons are back - a 50, 75 and 100 mile 'beast' with a difference! Whether you're a seasoned ultra runner or a complete first timer, here at Phoenix we aim to create an awesome running environment which is safe, inclusive, friendly and fun and allows you to achieve things you perhaps never thought possible. We will support you to succeed! Firstly, you get up to 30 hours to finish the event - that's right from 8.00am on Saturday 20th June right through to 2.00pm on Sunday 21st June, so if you fancy having a go at your very first 50 , 75 or 100 miler, or perhaps your first time running at night, then you won't find a longer cut off time anywhere. The route is a single 1 mile loop, which we've made as flat as we possibly can and just to add to the fun we have a 12/24 hour event and half / marathon events going on at the same time with other runners coming and going to keep you company. When you get to 50 / 75 / 100 miles you'll be a Finisher and get the epic Minotaur, Hydra or Centaur medal/buckle! The event is fully chip timed so you don't need to worry about keeping track of laps - we'll do all of that for you and can tell you exactly how far you've run each time you pass the awesomely well stocked aid station. Places will be strictly limited so don't leave it too late to enter. Off road trail, through the wine estate on a flat 1 mile route. Flat, with slight cambers.

The Denbies Marathon & Half Marathon is back for 2026. Firstly, you get up to 30 hours to finish this event - yep you read that right - from 8.00am on Saturday 20th June right through to 2.00pm on Sunday 21st June, so if you fancy having a go at your very first Marathon or Half Marathon then you won't find a longer cut off time anywhere. But the fun doesn't stop there because we're offering completely flexible start times from 8.00am Saturday right up until late morning on Sunday 22nd, which means that if you start later, say at 11pm on Saturday, you could try your first evening or even night run. You can also run more than one half marathon or marathon if you like, by simply entering the event more than once and starting when you like within the start window. The route is a single 1 mile loop (with an extra bit for the 0.1 or 0.2 miles required to run a half marathon or marathon), which we've made as flat as we possibly can, and, depending on what time you choose to start you'll have up to 24 hours to run your marathon or half marathon. The medal for this event will be a 'pick n mix' meaning we'll have a selection of epic medals for you to choose from.
