May I suggest this as an alternative to no gears at all, which in my opinion is a little silly. All the do da's are internal so no maintance. Its Sturmey so it will out live the bike, you and your kith and kin.
It is one of the great irony's of sport that no sport makes you strong enough in and of itself to do the sport. Swimming, football, running cycling even weightlifting, you have to do strength exercises to be strong enough to cope with the stresses you put your body under. Its in part because sports require repetitive actions and the body will break long before simply running or kicking makes your tendons and muscles strong enough to deal with it. If you want to progress as a runner in terms of mileage, endurance stamina and speed you will have to strength train because while you will get faster without it you wont stay fast for long. You will get injured and/or suffer from very long recovery times. You will find you wont be able to do the full range of training in a week and find it hard to increase mileage.
I do strength training now thats not too dissimilar to that described above though with out weights. I will be getting some though.
Sticky flex your right foot. Now grab hold of your right ankle tight. Now trying to move your foot. Does'nt move so well does it? That's what compression clothing does. It is meant to restrict movement. It gives support to injured muscles, and tendons during the healing process. Unless your an experienced runner you will not have consolodated your running form enough to still run fore footed restricted or not.
