One of Nottingham's key sporting events, the Outlaw has become (almost) even more legendary than Robin Hood, the Major Oak and Brian Clough!

Those who have conquered the Outlaw Triathlon are remembered in local folklore for having outwitted the Sheriff to complete a 2.4 mile swim, 112 mile bike ride and 26.2 mile run. As long as you can cover the distance in 17 hours or less, you will become an Outlaw. Six men have completed it every year since the Outlaw was launched in 2010; can they come back and finish it for a ninth time this year? And will you be joining them as a competitor or spectator?

The event begins with a mass swim start in the Regatta Lake at Nottingham's National Water Sports Centre. It’s an out and back swim course which is easy to navigate. With transition right next to the swim exit you'll have every opportunity to set a super-quick time and even faster escape onto your bike.

The roads around Nottinghamshire are ideal for fast riding (time trial bike friendly) and there is only the odd short climb to challenge you, but don’t underestimate the wind!

On returning to the National Water Sports Centre our merry men will rack your bike and see you out on to the flat run course around the lake and on to the River Trent path. You'll pass Trent Bridge, the City Ground, Wilford Suspension Bridge and the Victoria Embankment. The multi-lap course, which has been measured by UK Athletics, offers a feed station every mile or so, and is lined with supporters willing you all the way to the finish line.

On arrival at the finish you will receive a hero's welcome and be crowned a modern day Outlaw. Then you can enjoy the festival atmosphere with thousands of spectators cheering the athletes home until the sun finally sets on a spectacular day of racing.

Outlaw has been recognised as 220 Triathlon Magazine's Event of the Year in 2011, 2012, 2013, 2014, 2016 & 2017 and British Triathlon's Event of the Year in 2011.

Outlaw Triathlon route

Can I swim the course in advance?

The lake is not open for general swimming. There are events in the lead up, such as the Nottingham Triathlon and the Outlaw Half Nottingham, and OSB run a free Outlaw swim practice session on Saturday 28 July.

Is the bike course hilly?

No, not at all. There is only one short climb and the rest is relatively flat. However, beware of the wind! The winds can make it a tougher day in the saddle than you might expect. This course is perfect for TT bikes if you have one.

Are the roads closed?

Most roads are open but there are closed lanes on busy roads, managed diversions for cars and managed junctions for cyclists.

What is the run surface like?

Mostly tarmac and hard packed stones along the river path.

Do you get people who don’t make the cut off?

Yes, but not too many usually. A few will miss the swim cut off and those that miss it on the bike usually have had multiple punctures or exhaustion. It’s worth getting new tyres a few weeks out and get your bike serviced. TFN do bike checks over the weekend but don’t leave it until the day before if your bike hasn’t been serviced in months.

What are the event cut off times?

You have 17 hours to complete the Outlaw. You need to be out of the swim and on the bike course within 2hrs 15 of the start, which is 8:15am, and you need to be back into T2 by 4pm – this is due to us need to re open parts of the course which have closed roads, so there is no margin for error on this.

  • Did the Iron distance in 2019

    One of the best event this year. The staff an volunteers we're amazing. They managed to turn the event up to 11 after the bike section got cancelled due to flooding. The whole weekend was ace. Thank you OSB events,
  • Did the Iron distance in 2019

    I loved every minute of it. OSB are amazing organisers and the best feeling is when the team remember you especially Louise. HPP is and awesome site and I love the sprint that is held there too.
    I did the swim at both the half and full. But in 2021 when I am 50 I will do the half if I can get in.
  • Did the Iron distance in 2019

    I have completed 2 Ironman UK full distance tris. Outlaw 2019 was my 1st Outlaw event, I obviously can't comment on the bike course as that section was cancelled due to the extreme weather conditions making the roads un safe for cycling.
    I thought the briefing was quite vague and light hearted compared to other briefings I've attended, there was no mention of drafting rules and I was surprised to hear that those electric bikes are allowed at Outlaw.
    The transition tent is mayhem, the tent could be made much better so that the athletes can flow through the tent much easier.
    The swim was horrendous! In my opinion it would be a much better experience if Outlaw did a rolling swim start rather than having 1600 swimmers in the water doing a mass start.... the mass water start was bedlam and the Lake is too narrow to accommodate this volume of mass starters especially on the 1st lap and the Lake is very shallow towards the shore! 2nd lap was better as it became a rolling swim as you re-enter the lake.
    The marathon was not enjoyable due to the flooded paths and narrow paths along the trent and over the bridge. It wasn't an easy marathon due to us having left the swim at 7:30am to be told the bike was cancelled and we would be running at 9:30am now... by the time I started my marathon 2hrs 19mins had passed, I dried off best I could but it wasn't great.... now I'm full of a cold 😂.
    We can't control the weather but the swim start should definitely be a rolling start and possibly revert to 1 big loop rather than 2 small loops
  • Did the Iron distance in 2019

    Having been dealt a wild card by Mother Nature the team did a grand job ensuring everyone was safe and still managed to get us a swim and run
  • Did the Iron distance in 2019

    Great organisation from start to finish. Good communication, support/feed stations were the best. Atmosphere rating based on the support crew, not many spectators due to the appalling weather. Loved the event and will definitely be coming back next year.

    Did the Iron distance in 2019

    The race was amazing. The heavens opened up and the organizers stepped up. Yer the ride was cancel due the safety of the course. But every one involved stepped up and made the best of a bad situation. 10/10 for quick thinking and organisation
