Australia has many long rivers well suited for Marathon canoeing with races conducted over distances of 10 km and greater. There are various levels of competition for marathon paddlers at all levels from new paddlers to experienced veterans. The pinnacle of Marathon Paddling is at an international level  and a good summary was provided by OTV's show Race Day. The show is on YouTube in two Parts:

National Championships are raced over various distances depending on age category. The races are organised in traditional canoe classes e.g. K1’s, C1's and TK1’s, TC2's etc. The 2015 National championships were hosted by Burley Griffin Canoe Club and were be conducted by Australian Canoeing, PaddleNSW and BGCC. These are traditionally held each Easter, with the 2017 Nationals held in Sydney, at the Sydney International Regatta Centre (SIRC). The 2018 Marathon Nationals are to be held in South Australia at West Lakes, from Friday 18th to Sunday 20th May.

State Championships are also held in age categories and traditional canoe classes as for Nationals. Details for the State Championships can be found by clicking on the PaddleNSW web-site. The 2017 State Champs were held on the Molonglo River, hosted by BGCC.

The Paddle NSW Marathon Series is conducted by PaddleNSW and is a series of races conducted in eastern NSW. BGCC has been the series champions for 2012,13, 14 and 15 and are keen to defend the title again. The calendar for the 2016 series is below with more details on the  PaddleNSW website. This series is divisional, based on your previous results so  you are always competing against paddlers of similar ability.  This is a good format for both novice and experienced paddlers.
