The river is typically low around the race date. 35-70 cumecs as measured at the Otarama Gauge - The race day river flow cut-off is technically 180 cumecs, but also depends on associated weather factors.
The river is classified as Grade 2 with braided river and gorge characteristics. You are likely to encounter wave trains, strong eddy lines, bluffs, braids midstream rock hazards and tree hazards. From the put in, paddle downstream on generally easy grade 1 riffles with multiple braid options. Good river reading skills will help you take the most efficient and fastest lines. After about 30 minutes you will reach 3-4 Rock Garden Rapids. These change annually, but usually involve a mixture of manoeuvring arond boulders and punching larger waves.
At 15km you pass the Gooseberry Stream Checkpoint. This is the last opportunity to exit the river prior to committing to the Gorge. Another 10km of braided style river will see you at the Esk Checkpoint and the beginning of the Waimakariri Gorge. The gorge is about
30km long and consists of larger wave trains, bluffs and boily eddy lines.
If the river is higher there are more options, often with ’chicken routes’, but as the river drops in volume the options become fewer and the rapids more technical. The Gorge is absolutely stunning and if you are comfortable in your boat it will be one of the highlights
of the race. Significant landmarks to look for are Hamilton Rapid at the mid-point of the kayak stage, and the Red Staircase Viaduct which is two thirds of the way through the gorge.
The Woodstock Checkpoint marks the end of the gorge and the beginning of the final 15km braided section. Willow tree hazards are prevalent in this section. Stay focused on good route choice and avoiding tree hazards.
The exit is on the river right immediately downstream of Gorge Bridge. Get out of your kayak, leave it with your support crew and cross over the timing mat. Run up the track that starts near the bottom of the gravel road on the right by the permanent toilets, go around
the outside of the trees in the centre of the transition area to your bike.
River Safety Notes
If you are expecting to swim you should be paddling a more stable boat or getting more time on Grade 2 water. A swim will cost you 15 mins, a lot of energy and exposure to unnecessary risk. Your ‘faster’ boat will need to have an outboard to make up that swim time!
River safety personnel are stationed at known trouble spots on the course. They are not everywhere, and are primarily there for emergencies.– expect to self-rescue if you swim. If you see someone in trouble, please help them whilst ensuring you don’t put yourself in danger. Communicate any issues you see to next downstream river safety personnel.
Having an understanding of international river signals is important. Officials may use them to communicate hazards or direct you to preferred lines
Jet boats are used as part of our safety management system. They are important for the transportation of officials, rescuing competitors, radio communications and evacuations of injured competitors. Jet boats require less water and produce less wake when going fast.
Verbally communicate your bib number to check point officials and/ or paddle close to enable a clear view of your number. Paddle between bouys at timing mats.
Look for and follow signage. This is aimed to keep you away from hazards and within the managed river braids.
If you exit your kayak and end up on the riverbank, please be aware that 80% of the kayak stage is only accessible by jet boat. Depending on your location, it may take some time for officials to reach you for a rescue. If you’re unable to continue paddling, you will likely need to remain with checkpoint crew until you can be safely transported off-course, which may only happen once the tailend Charlie has passed. To stay warm while waiting, please put on your compulsory clothing.
