Cyclists in Bogota (Bogotá)

Hi
I recently moved to Bogota from Australia. I'm a keen cyclist and would like to meet other expats and fellow cyclists in Bogota to get out on some rides with. Would be great if we could start up some type of regular bunch/group ride - or even organise day trips to other places to ride/mountain bike. If anyone out there is interested, I'd love to hear from you!
