Lake Placid 100m super sprint rollerski race

For the 100 meters, the nordic world's record is just a little over 11 seconds.  However, this video reminded me that in the early 1980s, on a single day, Bill Koch broke the running world records for all distances longer than 200 meters up to 50k. (No secret to skiers, but cross country skiing is definitely faster than running.)
