The Phoenix Leviathon 50 Ultra is back for the third year and it's still a monster and this time we're bringing it to our epic Harlow route!

Whether you're a seasoned Ultra runner, or you fancy having a go at a 50-miler and have yet to conquer the distance then this is the event for you.

We're delighted to be hosting our next 50-mile ultra run and it's named the Leviathon, as a play on words, because we think it's a bit of a monster; a bit of a mythical sea monster to be precise!

The Leviathon is a 50 mile lapped event which will be hosted at the same time as our ROAR-some Romp meaning that you have an �on the day' fall back option. For anyone who completes a full marathon distance of 26.2 miles (in the Leviathon event) and then decides to stop at that point, then you effectively drop down to marathon distance. This will be allowed on the day with no prior notice and you will still be classed as a marathon finisher in the ROAR-Some Romp event and receive that awesome two-part magnetic medal and, of course, a published marathon finish time.

Otherwise keep going to complete the full 50 mile ultra!

And the medal ... well, it really is a monster!

Places will be strictly limited so don't leave it too late to enter.

We provide a physical running service and by entering our events you are purchasing an actual run, either by attending our events or by running the event virtually yourself. All participants in our events, both attended and virtual, will receive a free giveaway medal / memento from your run.
