The Riverhead Backyard ReLaps Ultra

2nd April 2022

Who will be New Zealands’ Last Person Standing?

Complete one 6.7km lap within an hour, restart again on the hour….continue…until only one person is left to complete a lap.


Start either the ultra or the relay and you will go into the draw for our major spot prize – a weekend use of an Amarok.  We’ll announce the winner on the Sunday after the 24hour relay finishes.

With 190kW under the hood and 580Nm of torque, the Amarok is more than capable of handling anything you throw at it, and as we know… tough comes from within.

Summary of the Ultra

  • Starting at 7am Saturday 2nd April 2022

  • Runners will start a 6.71 km (4.17 mile) on the hour, every hour

  • Runners must finish each lap within 1 hour

  • The next lap starts on the hour every hour after that

  • This continues until only one runner can complete the lap within the 1 hour time limit

  • Runners are called into the starting corral at 2 minutes to the hour

  • Any runner not in the starting corral for any lap is not eligible to continue and is recorded as DNF (did not finish)

  • Any runner who fails to finish a lap is recorded as DNF (did not finish)

How long is this likely to go on?

Past Riverhead Backyard ReLaps Ultra Events have been won by:

  • 2021 Chris Bisley did 38 laps (255km)
  • 2019 Katie Wright did 30 laps (201km)

Internationally the record is 75 laps (502.5km) by Karel Sabbe from Belgium.

Event Director of the United States event and founder of this type of event Laz Lake is renowned for dreaming up events to test people’s limits.  During the US event Laz posts updates on the Facebook page throughout the event and he sums it all up as he wrote during the final hours…

hour 66: and then there were two
with the passing of gavin woody,
it all comes down to johan steene and courtney dauwalter
one will get everything
and one will get nothing.
life is not fair in big’s backyard.
but you know the deal when you sign up.

The Road to Big’s (the World Champs of Backyard Ultra)

With the popularity of the backyard format there are now hundreds of backyard ultra events now.  Because of this, there is no longer any golden tickets directly into the Big Dog’s Backyard which is considered the World Champs of this format event.  Instead there is a pathway as detailed on the Backyard Ultra Website here, but recreated below:

We run in the backyard for many different reasons. We run because it is fun. We run to socialize with our friends (old and new). We run to go further than we have ever gone before….

But, for many of us, we run because we want to eventually go to Big Dog’s Backyard, and pit ourselves against the best in the world. And why should we not harbor such ambitions? In the backyard, anyone can win. One of the fundamental imperatives for any sport is to leave the outcome in the hands of the athlete. And so we want it to be in the backyard. Your road to Big’s is below. Along the way is the opportunity to represent your country on a national team, to compete for a national championship… and, of course, a clear path to reach the world championships in Big Dog’s Backyard.

In summary, you will find in the Brackets (rounds) for your country a list of Bronze and Silver Ticket events. The winners of the Silver Ticket events will have a place on the national team. New Zealand does not have any bronze events because we only have 3 silver events s there is no need.

In addition to the places on the team secured by winning a Silver Ticket event, there will be places for At-Large additions to the team.  As an example, the 15 man US team will have 6 places determined by the winners of 6 Silver Ticket events. The other 9 places will be determined by the top results on the At-Large list. A good result in any event you run during the qualifying period (which began August 16, 2020 and ends August 15 2022) can place you on that list. The top 9 performances, outside the winners of the 6 Silver Tickets, will earn those runners a place on the team.

The World Team Championships will start on October 15, 2022.

You will be both representing your country as a member of the team (ALL members are scoring members) and competing for the individual National Championship.  The Team Championships were first held in 2020, with Belgium winning, the USA second, and Mexico third.

World Individual Championships

The top 50 winners of the national championships will secure berths at the World Individual Championships to be held at Big Dog’s Backyard starting October 15, 2023. In addition to those champions, there will be an additional 25 runners selected from the At-Large list… the top performances of the previous 2 year qualifying period (August 16, 2021 to August 15, 2023).


The event is in Riverhead Forest. The event centre is just off Ararimu Valley Rd.  Take Old North Road through the western side of the Riverhead Forest and turn down Ararimu Valley Road which is on your right.

Please park as directed.

Once you’ve finished your event you’re welcome to stay at the venue and in your tent site, cheering on the other ultra and/or relay runners.  In fact, we encourage it!


The course will be a 6.7km lap through a mix of commercial pine forest and native bush.

The course has around 160m vertical gain per lap, but unlike past years its earlier and mainly all in one go!

Lap times start and finish under the start/finish gantry.

Click on the image below to go to the Strava segment of the 2021 course – this was tweaked a little from the 2019 & 2020 courses to make it smoother, take out some of the more gnarly quad busting downhills.

Alternatively look at the course in more detail and download a GPX file…[here]

The same loop will be used for the day and night!!


  • Runners must finish the lap within 1 hour

  • The next lap starts on the hour every hour after that (signaled by the bell)

  • Participants must be in the starting corral at the bell

  • Warning will be given at 3, 2, and 1 minutes prior to start

  • Runners may not leave the course until each loop is completed  (once the horn goes you must complete a loop before any support is given/taken)

  • No non-competitors on the course (including eliminated runners).

  • You are not to receive support or pacing from relay runners – gear, food or liquids.  All that is allowed is a quick verbal encouragement as they pass you or you pass them.  Both yourself and the relay runners will be disqualified if this rule is broken.

  • No personal aid/support during a lap (the one aid/support location is the event base)

  • No artificial aids (including poles!).  Music is okay but we ask that you’re aware of other runners so as not to hold people up, especially once the relay starts because they fly past the Ultra runners.

  • Slower runners – please allow faster runners to pass

  • The winner is the last person to complete a lap when all others have given up

  • All others are technically DNF

  • If no runner can complete one more lap than anyone else, there is no winner

  • Please report to the timing area when you decide you can no longer go on

  • No cats, dogs or other domesticated animals allowed on the course with runners.


Because of the lap nature of the course there is no compulsory gear required.


We recommend the Riverhead Backyard ReLaps Ultra runners have support crew. This is limited to a maximum of 2 people at a time (based at the runners support tent).  We’re happy to relax this a little after 12 hours and the numbers are reduced and there is more space.

General supporters can cheer/encourage/kick up the arse at the finish line etc but can not join the runner in their tent. This is to prevent overcrowding on the course around the tents.


We welcome spectators to come and have a look and support all the runners, however this is at the event centre only.  No spectators are allowed out in the forest, as they may be deemed support for a runner and may result in that runners disqualification.

Please be aware of the limited resources we have had to bring on site, e.g. toilets and water which participants have helped pay for so, they should have priority.

No dogs are allowed in the forest or at the event centre please.


There will be no aid stations or any water provided out on the course – you’re on your own, in this regards, when you’re out on the lap…its only 6.7km!

There will be water available for participants at the event base.  We are cup free so please bring your own vessel for holding water.


Each individual will be allocated a 3m x 4m site within the event base.  No vehicles will be allowed on the tent sites.

Individuals doing the Riverhead Backyard ReLaps Ultra will be given sites closer to the finish line.

Team tent sites do not have power or water.
