Charity fitness events

Am I allowed to post my sponsorship link to ask people to sponsor me.
I will be trekking my closest mountain on the 16th of June for WaterAid200.

Wateraid is a really good charity, not only supplying fresh clean water but helping villages create and maintain toilet systems and water systems so they can become independant.

I will be trekking a mountain called The Wrekin, it's quite small but it's my very first charity attempt and I'm excited yet nervous!
