Köping is on 59° 30′ 50.54″ N and the entire route runs north of that. But don’t be scared, in the summer this part of the northern hemisphere can be warm enough for the most of us. The amount of climbing is very moderate compared to many ultras in central Europe, and a lot easier than the roads of the Race Around Ireland. Nonetheless is is a challenge and mind you, it’s a beautiful piece of race.
The SUb610 can be seen as a convenient weekend event. It is suitable if you want to find out what ultracycling is about without investing to much of anything. Finding a crew if you are a first-timer is much easier if the race is short.
