Last ski season Ski Roundhill put up a $500 prize for an inaugural Ski-Doo Hill Climb, understood to be the first of its type in the country.
About 22 snowmobile riders screamed up the steep 1.7km Richmond Range course, with two actually making it to the top.
But this year (August 17 or 18 depending on weather) there's to be a bigger hill climb event at the same venue, with more in the way of sponsorship and prize money.
Organiser Simon Murrell, who is ski manager at the Roundhill Ski Field, Lake Tekapo, says snowmobile enthusiasts from around the country have indicated they'll be there.
