Where do I post Sportives?

[KidsCan]

Hi All,

This may seem like a silly question but I didn't want to tread on anyone's toes by putting this in the wrong forum.

We hav a Cycle Sportive happening in October and I'd love to get as many of you involved as possible.
The only thing is I wasn't sure where to put it

Any suggestions would be very much appreciated
Many thanks

Chris
