B-Max is beginner and sprint MTBO rolled into one. 1km and 2km course round Petone's Hikoikoi Reserve, 5km course up the river. It's a re-run of a 2017 event but now on the cellphone app MapRun. Riding is non-technical and flat so fancy bike not required. And suitable footers too - yellow level navigation.
