Mountain & Beach OSJ Grand Prix + Self Discovery Adventure

OSJ Grand PrixSometimes, you come across sports events that look like they’d be pretty fun, but they are just too far away to make it worthwhile to do just a trail run, a mountain bike race, an aquathlon or a speed climb. What if you could spend a weekend in a beautiful part of Japan ticking off each and every one of the above?

That’s exactly what this “Power Sports” weekend in Tottori offers at the end of September.

Those who take part in the OSJ Grand Prix event can do each of the events over two days, Friday September 19 and Saturday September 20, with points awarded to the top 20 finishers. The competitor with the highest number of points after the 5 events will win the Grand Prix.

Those who want to try all 5 events will need their own transport as the event sites are fairly spread out (head to the bottom of this page for a map showing all the event sites). The organisers will, however, provide kayaks for free and make climbing gear available for a rental fee.

It sounds like a great way to experience a variety of outdoor sports, chaco out Tottori’s beautiful scenery and, no doubt, meet some cool people. Why not combine it with a trip out to Tottori’s famous sand dune?
