Tarawera Ultra-Trail by UTMB: Route, live tracking & how to enter

The Tarawera Ultra-Trail 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. 

Date, start time and live tracking 

The Tarawera Ultra-Trail by UTMB traditionally takes place in February, with the 2025 edition taking place on February 15-16, making it the second race in the 2025 UTMB World Series. 

The event will welcome more than 4,000 athletes across one of four distances – 21km, 50km, 102km and 100 miles (165km).

And the 102km race is once again a HOKA Golden Ticket qualifier (2 M/F) for the 2025 Western States and has attracted an exciting line up of elites from around the world for the event’s hero race – more details here. 

Tarawera Ultra-Trail begins at 4:00am local time on Saturday 15 February for those taking part in the 100-mile race, with athletes given a total allowable time of 36 hours to complete the course. All other distances also start on Saturday, with the 50km and 102km races underway at 7:00am and the 21km at 10.00am.

Live tracking is available on the UTMB Live website here. 

Tarawera Ultra-Trail by UTMB route 

The Tarawera Ultramarathon by UTMB has four races; the T21, the T50, T102, and the TMiler. 

The TMiler is the Tarawera Ultramarathon by UTMB’s 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 race 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 TMiler route North-East of Mount Tarawera, which they will then follow to the finish in Rotorua. 

The T50 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 T21 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 TMiler offers four running stones to finishers, with the T102 offering three, T50 two and the T21 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 Ultra-Trail 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 TMiler to choose a permanent race number.

Tarawera Ultra-Trail by UTMB records and past winners
