Derek Alberts runs around Sandton - in a Speedo!

Johannesburg - Talk Radio 702 sport's presenter, Derek Albert had to face the music (and the streets of Sandton) after losing a bet.

Last week Derek said that if the Springboks lose to Japan in their Rugby World Cup game, he would run around naked.

Needless to say, he lost. And while SA is still mourning the loss, dear Derek did bring us some relief.

Although he didn't do it naked (lame) he did wear a Speedo and ran through the streets of Sandton.

Also, in the process he managed to raise some money towards charity.

Not too, shabby...

Run done! A bet is a bet. Japan weren't the only winners. Thanks to @Hollard for 10K each to @GRASSROOTSR & @CANSA cc.@gwalax @Radio702
