Cycle more often
If you’re new to cycling or have a basic level of fitness, the most important thing you can do to get fit is to spend more time on your bike (or buy a bike!).
It’s worth noting that you should build up your mileage gradually to avoid risk of injury. On training runs, try adding one or two kilometres a week to your rides and try and get out at least three times a week. Decide which types of ride you’re aiming for and tailor your mile building accordingly.
As well as building mileage, try to ride day after day – this will get you and your body used to the bent over body position and to sitting on the saddle. That way it won’t be such a shock to the system and you’ll be able to make the most of the ride.
