it is a charity event ... i think you can do sponsor walk or anything with wheel. Either bike, skate, roller blade whatever.

not too sure what to expect this year, but last year there was a stunt bike, football show, and some other things.

it is just something to do in Doha ...

The money will go to ROTA (Reach Out To Asia).

The entrance was free for last year, no idea about this year.
