The SILVA National Orienteering League turns 18 next year and it just gets better with age. The four round, 18 race competition will feature quality maps close to major cities and is sure to draw big numbers.
Round 1 will feature the return of the Eureka Challenge Massed start Hagaby in complex gold-mining terrain. And the Mixed relay is back after a years rest and is sure to be a highlight of the season.
Round 2 is the Easter 2010 carnival based around Canberra, and the ACT Championships in Buckenderra near Cooma.
Round 3 is the traditional WOC trials in May and will feature Macquarie University, one of the best sprint maps in the country. The middle and long distance races will be in the Southern Highlands’ rugged Sydney sandstone terrain.
Round 4 is the Australian Championships Carnival near Adelaide, South Australia. SA hosted the 2009 Round 1 and if those races are anything to go by you won’t want to miss the 2010 Aussie Champs.
The final 5 races of the 2009 SILVA National Orienteering League start in Victoria in just a few weeks- for all information checkout the Bushrangers 09 carnival website.
