Two crews.
One series.
WARU-X started with two events that already worked: a 500-person race in Christchurch and Race Wānaka. Put together, they showed what New Zealand was missing: a national series of fitness races.
From Hagley Park to a national ladder
In October 2026 Blair Williamson's Limit Zero, a successful fitness racing training club in Christchurch, ran a full race simulation for 500 people in North Hagley Park.
At the same time Grant Straker, a successful New Zealand tech entrepreneur, was running Race Wānaka.
Between them they saw the opportunity: races close to home, run to one standard, with results that count across a whole season. So they started WARU-X. Nine rounds, one ladder, and a final in Wānaka.
The road to Wānaka
Who's behind it
Blair Williamson
Blair runs Limit Zero, a successful fitness racing training club in Christchurch. Limit Zero ran the 500-person simulation in North Hagley Park that showed the demand was there.
Limit Zero hosts both Christchurch rounds and is the series' equipment partner.
Limit Zero ↗Grant Straker
Grant is a successful New Zealand tech entrepreneur. Grant runs Race Wānaka, home of the curtain-raiser and the WARU-X final.
Grant's new company, Splitline, builds the technology behind the series.
Race Wānaka ↗Splitline
Splitline builds technology for timing fitness racing, and runs fitness racing events.
Every WARU-X entry, time and result runs on Splitline. That's how a finish in Nelson lands on the same ladder as a finish in Dunedin, live on the night. Splitline also runs seven of the nine rounds, including the final.
