Walking three kilometres one way, and then back is easy. It takes about half an hour for me. If I walk fast then it takes less time. For me, walking is easy. Using the foot scooter is more of an effort too because it requires the use of different muscle groups, than walking, cycling, and running.
I find that when I go a certain distance on the scooter my hip muscles get more tired.
Yesterday I went for a bike ride. When I looked at the route I thought “this looks like a nice calm, relaxed ride. It wasn’t. I rode with group 2, which is a fast group, going uphill at 20-40 km/h on certain segments.
You might look at a cycling route and think “this looks flat, it doesn’t go to the top of the Jura” but don’t let that mislead you. When you’re riding at the foot of the Jura it’s easy to climb, and then descend, and then climb again, and then descend, and then climb yet again.
On Wednesday morning I rode my bike into Geneva to drop it off for a service. In the evening I went for a group ride that was heading in the direction I wanted, before leaving the group and riding for home. I didn’t ride much on Wednesday, but I was tired. I believe that walking in cycling clothes, to catch a train, twice, does tire us more than walking in normal clothes.
