Sounds similar to what I am about to start in a month. I am really looking forward to it. We will be about 5 kilometers from my office. Downhill to the office, uphill back home. Elevation change - possibly 100 meters.

I too need to lose some weight - about 10 kilos. This should do it quickly - as long as I don't compensate.

However, I suspect my commute might take a bit longer - most of it is roads made of river rock smashed into clay by traffic. The bike might actually be quicker than the jeep - I suspect it will. There are some pretty steep areas - but most of it is flat.

Bike goes to the shop for a tune up. I have a Cannondale and there is an official repair shop here in Costa Rica. You all will kill me if I tell you how much it cost for a tuneup...

I think my commute as a little better scenery - this is an example of the roads that I will be riding. I do have to watch out for cows though.
