Have done a few AR races - they are super fun. The AROC ones are run very well. make sure you read all the info in the info pack, as it is self explanatory and helps.
Some tips:
Last year the event started with a mad scramble around Rafertys answer some questios before getting enough points to jump on the bike and go. The bike legs early are steep, good on quads.
On race day get there early for early rego, that way you then get your maps and can then mark out the route - it is not real hard. Take plastic laminating film to laminate the map after marking - then you don't worry about getting it wet.
Carry water bottles on bike, full with one water, the other powerade, etc.
The transitoion from bike to run is usually after a few CP's and then it is running along tracks, with the CP's usually hidden a little. if you ae not up front, keep an eye on the muddy tracks others leave.
Wear runners - there are too many transtions and too much on foot to use bike pedals. Use straps - nealry as good as cleats.
There was an orinteering section at caves - lots running and picking out points to answer.
The paddle went acroos lake mac to wangi - about 15 mins each way and oveer there another few CP's - we just bahsed thru bush to race the clock.
It is fun, can be long but I know you are fit - just give it a good shot. be careful not to miss a CP, if yopu do it can get frustrating and then it comes to decision time - lose a CP and get going, or get booked time??
No matter how good, it takes a few hours, up to 6, so take drink, food, etc. There are plenty taps near Swansea, Caves, where yuo can fill up, but no food - take your own. Be careful of sun, etc, and if it rains - get wet and MUDDY like last year.
