Q: I feel I am too old and fragile to rollerski. What should I do instead?
A: We suggest you hike and run with your ski poles and use them to push off with as you would when skiing. You can use the poles you ski on snow with, but it is better to use poles that are shorter than your on-snow poles. The exact height will be determined by the energy you can put into the effort. When classic skiing on-snow you would use a pole about 83% of your height. If you are just Nordic walking than you would use a pole around 70% of your height. So your exact dry-land pole length will be determined between 83% and 70% of your height by how dynamic your striding, bounding and poling is.
