The 4some challenge will target women aged 18-30. Next summer 80 teams of four will take part in competitions around the world comprising a 4km mountain bike relay, a 2km run relay and a 50-metre swim relay. The final will take place in Europe in September 2004.
The event organiser is looking for sponsors. Puma is in talks with MTV Networks Europe to host a series of post-event parties for the heats and final.
"4some was designed to push women to their personal limits and discover new strengths in a fun event," said a Puma spokesman.
