Andy Samberg and Chris Parnell sang a whole song about lazy Sundays ... and the movie The Chronicles of Narnia. For us, we prefer to spend our lazy Sundays waking up late and relaxing, but if we can throw a good deed in there somewhere, well, it’d be a perfect day. Thankfully, the Charleston Bed Race combines all of these. What’s a bed race, you ask? Grab a team of five, hook some wheels onto a mattress, decorate it to the nines, and get ready to roll through Hampton Park for about two city blocks, racing against an opposing team. And the term mattress is used loosely. Last year, one team used a hammock as their bed. “If you’re ready to come out and have a fun time laughing with the whole family, this is the day for you,” says Teresa Bishop, program for Camp Happy Days, which the race benefits. Beds will not only be judged on speed — fastest and slowest — but also on design. A People’s Choice Award will also be announced. After the champions are declared, beer and food from Kickin’ Chicken will be served. Kids can bounce on the jump castle or apply temporary tattoos at the kid’s zone.
