Tarawera Ultramarathon by UTMB — Rotorua, New Zealand

There were some 5,000 runners across the event’s different races. The 102-kilometer race, which iRunFar reported on in detail, was again the premier distance, but the 100 miler and 50k both had some star power too.

The 102k race was a 2023 Western States 100 Golden Ticket Race, wherein two entries each are given to the top women’s and men’s finishers.

Though race days had great weather this year, prior storms caused issues on the normal 102k and 100-mile courses, forcing those to reroute last minute. We believe the 50k and 21k races took place on their normal courses.


The top seven women all finished in quick succession. Nancy Jiang (New Zealand) was at the top of that group in 9:26, but it was close. Jiang just edged out Stephanie Auston (Australia) by 81 seconds. Auston finished in 9:27. Aroa Sio (Spain) was third in 9:30 as just 11 minutes separated the first five women.

There was a bigger gap at the front of the men’s race as Daniel Jones (New Zealand), and Hayden Hawks (USA) took off. At the finish, Jones upstaged Hawks with a 7:27 finish time that was well clear of Hawks and everyone else. Hawks followed in 7:42, and Ryan Montgomery (USA) moved into third with an 8:11 run.

Where only 11 minutes separated the first five women, the men’s gap was 56 minutes, thanks to Jones’s smoke.

Full results.

The next Western States 100 Golden Ticket Race is next weekend’s Black Canyon 100k in Arizona, which we preview later in this article.

100 Mile

Both Lucy Bartholomew (Australia) and Zach Miller (USA) led for the entirety of their races.

Bartholomew took the women’s crown in 17:13. Kimino Miyazaki (Japan) and Katie Wright (New Zealand) were next on the podium in 17:54 and 18:19.

Miller was racing his first 100 miler outside of UTMB, and on definitely different terrain, he ran a fast 14:41. Hajime Mamba (Japan) was second in 15:11, and Nicholas Bamford (U.K.) was third in 15:32.

Full results.

Allie McLaughlin (USA) and David Haunschmidt (New Zealand) set new course records in 3:43 and 3:33, respectively.

The top four women all came in under four hours on the fast course, and McLaughlin was 10 minutes better than the previous course best. Previous record holder Caitlin Fielder (New Zealand) was second in 3:47, and Kate Avery (U.K.) was third in 3:54.

Haunschmidt took control of the men’s race in the second half and pushed for a seven-minute lead on everyone else. Second-place Piotr Babis (Poland) finished in 3:40, and Charles Hamilton (Australia) was only 45 seconds behind Babis for third, also in 3:40.

Full results.

Additional Races and Runs

The Coastal Challenge — Costa Rica

The six-day stage race always brings in some star power, and for the women, it was a rematch from the front end of last year’s UTMBKatie Schide (USA) and Marianne Hogan (Canada) headlined the women’s race, and the pair finished day one together. Schide took the win on day two, and then on day three, Hogan dropped with an ankle injury. The men’s race was close at the start. Mathieu Blanchard (France) was consistently in front of Didrik Hermansen (Norway) on stages one, two, and three before Hermansen won on day four and then broke Blanchard on day five. Hermansen took the race’s fifth stage by 21 minutes. At the end of the week, and after 236k, it was Schide and Hermansen as champions. Schide totaled 30:30, and Hermansen finished in 24:26, 22 minutes better than Blanchard. Full results.

Joasia “Jo” Zakrzewski (U.K.) set a new 48-hour world record at this event. iRunFar separately reported on the performance in greater detail. She ran 255.7 miles during the fixed-time race, and that makes her the new U.K. record holder, too, regardless of gender. Full results.

Call for Comments

It’s Valentine’s Day eve, and I’ll throw it back to February 2021 for “Catching Up with Elisabet Barnes.” Those “Catching Up with” articles were so fun to write as we waited out a lack of racing during the COVID-19 pandemic, they are such interesting and diverse topics, and I can’t believe that one didn’t get a single comment! Let’s not do that again. Leave us some kind words below for this Valentine’s Day edition.
