I took this up after my Naturopath said I wasn't getting enough exercise it really took some time to get my fitness and endurance to an acceptable standard, but it also a good stress release.
1/ One hours bike ride is as good on a mild hilly route as it is on a longger flat ride.
2/ Bordom can be over come by changing routes every season.
3/ Some better bike shops have books available on new routes in your local area that can alleviate boredom of the same route.
4/ Good music playing makes the ride even better.
5/ The ride is more fun when the ride ends at a decent cafe.
