The Tarawera Ultramarathon by UTMB is a collection of UTMB World Series trail running races in New Zealand. 

Held in February of each year, the race is based in the town of Rotorua on New Zealand’s North Island, with the inaugural edition held in 2009.

In 2021, the event joined the UTMB World Series meaning it began to offer running stones to competitors in all four of its races, allowing them the chance to qualify for the UTMB World Series Finals at the Ultra Trail du Mont-Blanc

Tarawera Ultramarathon by UTMB route 

The Tarawera Ultramarathon by UTMB has four races; the TUM21, Bachcare TUM50, TUM102, and the TUMMiler. 

The TUMMiler is the Tarawera Ultramarathon by UTMB’s flagship 100 Mile race. Starting at Te Puia in Rotorua, it takes runners throughout the geothermal surroundings of the region, with competitors crossing eight different lakes (which includes crossing Lake Rotomahana by boat), running along single-track paths surrounded by Redwoods and navigating around Mount Tarawera before returning to Rotorua at the Lakefront Reserve. It has a total elevation of 5470m. 

The 102km TUM102 starts in an entirely different location, at Firmin Field in Kawerau – an hour east of Rotorua. From there runners must tackle 3089m of elevation as they first travel southwards to join the TUMMiler route North-East of Mount Tarawera, which they will then follow to the finish in Rotorua. 

The Bachcare TUM50 takes runners on a shorter journey around Rotorua, leaving Te Puia and taking runners southwards to Lake Rotokakahi and Lake Tikitapu before finishing in Rotorua once more. It has a total elevation of 1572m. 

Finally, the point-to-point TUM21 is a 21km race with 734m of elevation. Starting with a loop around Lake Tikitapu, runners will then race to the finish in Rotorua. 

Facts, tips and FAQ 

All four Tarawera Ultramarathon by UTMB races offer running stones. The TUMMiler offers four running stones to finishers, with the TUM102 offering three, Tum50 two and the TUM21 one.  

These running stones can be used to enter the lottery for entry to the UTMB World Series Finals at the Ultra Trail du Mont-Blanc. 

As a long running race, the Tarawera Ultramarathon by UTMB has a special ‘Legends of Tarawera’ programme for any athletes who have completed ten or more races at Tarawera Ultramarathon, offering gifts for 10, 15 and 25 races completed. 

Other rewards include an opportunity for those who complete the TUMMiler to choose a permanent race number.  

How to qualify and enter Tarawera Ultramarathon by UTMB 

All entrants for every race except the TUM21 must be 18-years-old or older as of the start of the race. For the TUM21, entrants must be 16 or older. 

Entrance to the TUMMiler costs NZL $950.00, with entrants required to provide evidence of a completed 50km or longer run completed before 1 January.

There are no such qualification criteria for the other races. The entrance fee for the TUM102 is NZ$525.00, TUM50 NZ$375.00 and TUM21 NZ$160.00. 

Tarawera Ultramarathon by UTMB records and past winners 

Whilst it only joined the UTMB World Series ahead of its postponed 2022 edition, Tarawera Ultramarathon by UTMB has taken place in some form annually since 2009. 

In 2009 the longest race was 85km, and the 100-mile TUMMiler was not introduced until 2018. In 2014, Cyclone Lusi meant there was an altered long (73km) and short (63km) course. 

Course records (over the current distances) are denoted like this.
