Getting There

This year's event is based in the South Eastern corner of the Akatarawas. The Event base and Start/ Finish area is on McCurdy's Rd in Totara Park: Click here for Google Map
From SH1 or downtown Wellington follow signs to Upper Hutt and then cross the Hutt River into Totara Park. Parking will be on McCurdy's Rd, and/ or the car park on the Eastern side of Totara Park Rd.
Unfortunately there is no coffee at the event base, so please come suitably caffeinated. There is cellphone coverage at the base. Nearest toilets are Upper Hutt Darts Assn just over Totara Park Road.

Maps and Score Cards

To cover the area we'll issue each person with two A3 maps. OK that's hard to handle on a bike, but you know track-builders. There are hundreds of tracks, many close together, and we want you to be able to see them on the map. The scale will be 1:20,000. This is enlarged a lot compared to the standard topo map, and has twice as many contours - 10m. Over the years we've mapped a huge number of tracks that aren't on the Topo or even Trailforks, but the pixies are out there as I write making more! We will claim 95 percent.

There will be a special enlargement on a separate sheet for Rallywoods.  There won't be many controls there, but we just couldn't ignore it! This will be at 1:10,000 

The tracks are approximately graded to a 4-point scale. Solid lines are gravelled. Long dashes are not, but can be nearly as fast if conditions are dry. Short dashes means "picking your way" and an average rider will be off the bike frequently. Dotty tracks means unrideable, again for an average rider, not Danny Mackaskill. We try and take the effect of slope out of the equation, so you can expect them to be worse uphill, better downhill.  

Most of the bush is mapped as medium green from aerial photos, though this covers pine plantation as well as native, so take local conditions into account before heading off-track. Open land is shown as per orienteering convention in yellow - think hay paddocks. And in-between vegetation such as scattered trees or scrub or logged/replanted pine forest is green dots in yellow. We've shown some favourable off-track travel in light green (forest) or bright yellow (open land), but this is from a foot point of view.You're going to be mostly on trails.

There are a couple of No-Go areas marked with the usual purple stripes plus a No-Bike area. This is enclosed with a blue version of the cliff symbol. The teeth point into the no-bike zone. Any controls inside are blue circles and blue numbers instead of the more usual purple. You may not take a bike into this area at all, not even pushing it.
There is one restriction on direction, a farm access track that may only be ridden UPhill. The allowed direction is shown by a purple chevron (arrowhead) on the track. This means for everyone, with or without a bike! If in doubt obey the "no entry" signage.
Being a REAL Ak Attack we'll be using Orienteering control flags and punches, and teams will carry cards with numbered boxes to record the controls that they visit by using the attached punches. There will be one card per team, so it is probably advisable to assign a team card puncher. These cards are a tough plastic coated card with holes in the corner, and traditionally have been attached to bikes using access card retractors.

ALL team members are honour bound to go to each control point together. Don't send your strongest team member up the hill while the others take a rest. It isn't fair, and besides it compromises our safety system which depends on the team being together.

Your Safety

Now you are there, we want you to have a fun day, but please note:

We do NOT have exclusive use of any part of the area. You may be using roads where normal road rules apply. You may be using forestry roads which may have logging trucks on them. You may be using part of the Karapoti course with people doing last minute training. You may come across hunters or motorbikes on both the main tracks and the smaller ones. Expect someone round every corner. Ride conservatively as if you will meet yourself coming the other way. Most tracks are two-way and other Ak Attack teams may have chosen your exact route in reverse. Parts of the course are remote, and external help will depend on getting a message back to base.

Note the compulsory equipment on the "What Is It" page.

The underlying safety measure is the team. The team must stick together except to obtain help in an emergency. Each emergency will be different but we would expect a cellphone call to the number on the map; an undamaged team member to get back to base; or get a message back to base with another team. Use the control numbers to help describe location. There is cellphone coverage over much of the course, but "Murphy's Law" says that your incident will occur out of coverage. An unaffected team member needs to move to get coverage - hills being more likely than valleys.

In case you get stranded out there we're going to get you to give us an intended route on a black/white copy of the map. Don't just go home, failure to check in will initiate a search. At base we'll have a 4WD vehicle which can get near most parts of the course and a first-aider.

The Name of the Game

Right, onto the fun stuff! Your objective is to maximise your score. The control points have different values, being the first digit of the control number multiplied by 10. That is, control 15 is worth 10 points, control 99 is worth 90. Control points will range from 20 to 100 points, in general the higher the value the harder to get but not always...

There's a severe penalty for returning late: soft at first then getting tough! The formula is N squared where N is the minutes of lateness. We've decided to forget about the seconds, if you're late what's 59 seconds:-)) So 1 minute late 1 point and that's neither here nor there. But 10 minutes late, that's 100 points off! Half an hour will probably cost you everything you earned. Highest score wins, in the event of a tie the earliest to finish wins.

And although this events has its roots in MTB-orienteering, here you don't have to stay with your bike! You can choose to dump your bikes (locking them together may be a good idea) and get certain controls on foot. You could for example do a loop in a steep area on foot, or visit a control on a no-bikes track. It's another element of planning your route. And since you can drop your bike this allows teams to do the event entirely on foot.

Fine Print

Things that don't fit anywhere else. While food and water on the course is your responsibility, we will list some known water sources at the start. Satellite-based navigation aids are prohibited, such as GPS's. This is a map reading adventure! However cycle computers without GPS are fine. If a team member has to drop out for any reason you must bring them back to base; and from that time you are a new team starting with a score of zero.

Some of NZ's fresh waterways have been contaminated with pests, notably Didymo. We must prevent these pests from entering this area. They can start off microscopically small - just one drop of water on a bike spoke or a damp tramping sock can be its way in. If your bike or footwear has been in South Island waterways recently, ensure there's no plant matter, and soak or scrub with 5% dishwashing liquid for at least a minute. Then leave them to dry for 48 hours. We expect the regional council will be helping us on the day with additional precautions.

The event is run by Orienteering Hutt Valley. The person in overall charge is Liam Drew
