The kicksled is a small sled consisting of a chair mounted on a pair of flexible metal runners which extend backward to about twice the chair's length. The sled is propelled by kicking i.e. "sparka" in the Scandinavian languages
If you are not Finnish you can buy yours during your visit ,as it is mass produced by ESLA a Finnish company
Since 1990 kicksled racing was revived as a serious sport in Finland. There are races of up to 100 kilometres (62 mi) long and the average speed is around 30 km/h (19 mph).
So avoid to say to a Finnish that is is a “Granny” sport …he will challenge you on a lake race.And your heart beat will jump so high during the run, that you will regret painfully your bet !...
