B-Max is beginner bike-orienteering suitable for families. See website above. For kids there will be a 1km course and a 2km course. All around the beachfront park and away from traffic. And you don't need a fancy bike on the flat.
Short courses also ideal for orienteers whose bodies can't keep up with their heads and longer courses are too easy. You'll be amazed how easy it is to lose time in Sprint-MTB-O! Off-track is allowed but its 65-75% path speed so route choice is fascinating. For you we recommend the 2km course plus the 5km course up the river to Sladden Park. We'll compute the Rider of the Day as 2X your 2km time plus your 5km time. We challenge you to beat the course planner whose result is 44-27.
And if you don't have a bike treat this as a U-Max ie DIY foot-orienteering practice. We'll have enough maps for the usual U-Max numbers and you can make up a course to suit. Entry fee $8/$4, free for coaches and chaperones. Hint hint bring a friend.
PS A mapholder is very useful on the bike, you can make one from a clipboard, cable ties, rubber bands etc. Or we'll have the bits to make one for $5.
