" no problem i thought.I 2 mile jog was my thought.Now i feel like ive been cage fighting ! I ache all over,is there a secret to this running thing ? Or is it just perseverance.
You ride a bike. You will probably have above average cardio-vascular fitness.
You ride a bike. Some, but note, only some, of your leg muscles are well trained for running.
You ride a bike. Unless you ride CX or do real MTB'ing your upper body does cock all.
You ride a bike. The motion of the pedals involves no impact on joints or soft tissues of the lower body.
You ride a bike. Your running cadence will probably be too slow, cycling ain't great for leg speed, and you may be over-striding as a result.
You'll adapt, over time, if you persevere, and if you don't try to run too far or too fast; either and both of which is a recipe for getting injured. Stick at it, but be prepared for your son to kick your 'arris.
For me the scenery goes by slower, but the mental freedom/liberation is greater.
