ST. CLOUD - St. Cloud's Alise Post  is enjoying her first trip home since her Olympic debut in London earlier this summer.

The 21 year old BMX bike star spent Saturday afternoon at Pineview Park BMX, signing autographs.  She says it's been great to be back and  spend time catching up with friends and family.

While catching up with her friends and family is a major bonus, Post says that's not the main reason she's come home this weekend. Post and Pineview Park BMX will be holding a bike race with a goal of raising $10,000 to fight Multiple Sclerosis.

The day will include a silent auction of Olympic and pro BMX gear. To check out the line-up, visit their website.
