My commute is just over 23 hilly kilometres each way - about 14miles.

But even if it was twice as long each way (46km/29miles) I would still find the time to do it.

Make sure you can build the time in to your day... but the biggest thing is to make sure you can do two reasonably big rides in your day. Remember your body has to recover in between rides... you need to rest, to eat and drink properly.

When I first started cycling, and then commuting occasionally, I would take my car part way and bike to/from there as the worst hills are near home and I just didn't have the "oomph". Lisa's suggestion is a good one.

The other thing I do still when I dont want two rides in one day is I take the car to work, leave the car in town and bike home. The next day I bike to/from work. The third day I bike to work (this is a good recovery ride as it is heading down to sea level so not too many hills) and I drive home.

I dont ride in the dark, so a third option I use over winter is to bike to work, and get a lift home with someone from up the road.

Have fun finding a way to commute that suits you best
