The Holkham Estate and its magnificent eighteenth century hall provide a stunning backdrop to the swim, both transitions and the run. The bike course is a single loop taking in the coastal road, quiet country roads and some faster roads. The run does feature some climbs across three loops around the Estate.

There is on-site camping organised specifically for competitors and their family and friends, camping is only permitted in Holkham twice a year, so this is a fantastic opportunity. There are various types of accommodation in the area, but this is a popular holiday destination, so please book early!

This will be a very high quality racing experience, and an escape from everyday life. Holkham is one of Britain's tourist gems, and we're delighted to be able to return for a third year.

How to enter the Outlaw Half – Holkham

  1. 70.3 (Middle distance)

    Triathlon: Swim 1.2mi, Bike 56mi, Run 13.1mi

Outlaw Half – Holkham route

What are the cut off times?

Swim –  1 hour 10 minutes after your wave start, with a further 10 minutes allowed to reach bike mount Bike 5 hours 20 minutes after your wave start

Run – 9 hours 00 minutes after your wave star

Do people miss the cut off times, and if so what happens to them?

Yes, they do, but not many. A few will miss the swim cut off and those that miss it on the bike usually have had multiple punctures, exhaustion due to heat, or got too cold in bad weather. It’s worth getting new tyres a few weeks out and get your bike serviced. TFN do bike checks at the expo but please do not leave it until the day before if your bike hasn’t been serviced in months.

Anyone missing the cut off times will be asked to stop and be transported back to the venue if necessary. You need to be ahead of the cut off at all times, you can’t rely on catching time up later in the course if you are well behind it you will be asked to return to the venue.

How hilly is the bike course?

It’s undulating with a few climbs and some nice fast sections. Overall the roads are generally quiet with some technical sections. Open areas can be prone to the wind.

What is the terrain on the run?

It’s a fairly tough run and you need to prepare accordingly. The surface is a mixture of tarmac, concrete and sandstone. There are a couple of potentially narrow sections where you will be able to run on the grass if needed.

Where should I start on the swim?

Each wave will be around 300 people and will spread out really quickly, so you’ll have a lot of space to swim. If you are quick (25mins or below) you should start at the front of your wave. If you expect to be nearer the cut off, like your own space or are nervous then start at the back. After the first few seconds everyone will have sprinted off and you can start in your own time.

How should I pace the swim?

Fast swimmers will sprint off to establish space for themselves in front of everyone else. Slower swimmers should start slowly over the first 200-400m and then aim to work back up the pack gradually.

Kit List

What type of bike would you recommend using?

A TT bike with standard gears will be absolutely fine and those wishing to use disk wheels are advised to check the wind before making a decision regarding this. Road bikes are also absolutely fine with either compact or standard gearing – it’s unlikely you’ll need your small chain ring!


What can family do while I’m racing?

A spectator guide for the event this will be published in the immediate lead up to the event. Holkham Hall has lots of things to do, many people travel for many hours to spend the day at Holkham – you can simply walk around the venue, spotting lots of wildlife, including literally thousands of deer. You can visit any of the four wonderful cafes, stroll along the beach, just a couple of miles from the transition area. There is also the option to hire bikes, visit the awesome children’s playground and don’t forget on the race weekend there will be the event expo and food outlets to visit.


Are there separate Age Group waves & awards?

Yes, there will be Age Groups waves, likely starting from 6.30am through to 7.30am. Expect there to be approximately 250-300 competitors per wave. There are prizes for the top 3 in each category. There is a separate elite wave, which the fastest competitors can elect to go into based on their previous results.
Note: your age group is decided based on your age on 31/12/2018

Can I train on the course?

You are not currently allowed to swim at Holkham Hall during the year, it is only permitted during the race weekend. We will know closer to the event whether a training swim will be available but note that this has not been possible in previous years.

The bike course uses some beautiful roads, which you will be able to ride whenever you wish. Remember that they will have traffic management on the course on race day, so it will be more suitable for racing than it may appear during a visit in the lead up to the event. We would recommend that if you are riding the whole course for a training ride, that you take extra care on the A148 & A149 as these roads can be busy at peak tourism times.

The run course will be difficult to cover during a training run. However, there is a Park Run based at Holkham Hall, which uses a very similar route. The run route will have 3 laps & three feed stations per lap. The run is fairly hilly, we recommend you prepare accordingly!

What are the common mistakes by competitors?

Not knowing where their things are in transition – make sure to visualize your run out of the water and how to locate your bike, same again for T2.

Not arriving early enough. Remember there is a lot to do before a race and we check in every bike to make sure it’s safe and has the race stickers in the right places, this takes time so please allow for this and the inevitable toilet queue.

When do I have to register & rack my bike?

Registration will be open on Friday afternoon & all day Saturday. All bike racking will take place on Saturday afternoon only. There are no other options and you must bring photo ID with you.

Will there be live results / tracking?

Yes, they will run a live chat system as well as results tracking. Check for updates on this via our website nearer to the event.

Is there wifi at the venue?

They plan to offer a wifi system on site, which you can pay a small fee in order to access, this applies for spectators too. There is also wifi in the on site café. Note that generally phone signals within the estate are not brilliant.

    Did the 70.3 (Middle distance) in 2019

    My first 70.3 event and the Outlaw at Holkham is stunning, great swim but 'busy' to say the least, excellent bike course and tough but picturesque run with phenomenal support all around, sub 6hr as i wanted so really pleased. great marshals really helped .
  • Did the 70.3 (Middle distance) in 2019

    Another great Outlaw event. Quite lonely away from the house during the run, but great marshalls helped to fill the gaps. I'll be back again :)
  • Did the 70.3 (Middle distance) in 2019

    Norfolk is not flat, both run and bike course lumpy. The warning about risk of punctures was correct, carry spares and if camping at Holkham, beware no network on BT.. it was a long night.
  • Did the 70.3 (Middle distance) in 2019

    Excellent event all round. Would totally recommend as a first 70.3. Just don’t swallow the lake water, as I am currently suffering for doing just that! 🤢
  • Did the 70.3 (Middle distance) in 2019

    Swim; in a lake flat and easy but some pinch points.
    Bike; rolling Norfolk single loop
    Run: three loops of undulating tarmac, gravel and wood tracks.
    Typical friendly well organised Outlaw event.
  • Did the 70.3 (Middle distance) in 2019

    2nd time out at Holkham, and was an even better experience than last year. Survived the swim, blasted it on the bike and was relaxed on the run. Sub 6 hrs, job done!
  • Did the 70.3 (Middle distance) in 2019

    Fantastic volunteers make this event. The bike and run courses are tough but fun. The swim is pretty manky!....
  • Did the 70.3 (Middle distance) in 2019

    What a brilliant event! Wish the warning of flint roads had come before my bike was racked and locked away as would have used tubeless wheels and not the aeros (2 punctures). Volunteers were stars. While a 3 lap half marathon is hard psychologically it does mean plenty of on course support.
  • Did the 70.3 (Middle distance) in 2019

    This is a fabulous race. The setting is dramatic and interesting with a 1.2 mile swim in the lake which was a great deal clearer than in other years, a 56 mile bike around the rolling Norfolk hills and a tough 13.1 mile run at the end through Holkham park over 3 laps. The support is tremendous on the run with cheering crowds and the feed stations are brilliant too and very welcome. Transition is slick as is the start and finish with excellent chip timing. The only downside this year was registration which took over an hour while we waiting in the drizzle and the lunch at the end had a massive queue - both of which were absent in the 2 previous years. That aside it is a brilliant event.
  • Did the 70.3 (Middle distance) in 2019

    Brilliant day, volunteers were amazing. Quick bike course, beautiful run course with good support. Would do it again!
