Simo Santapukki is drummer, best known as a member of Apulanta, possibly the foremost rock band here singing in Finnish. He gathered this year's charity team, of musicians this time. Some of them had some O background, some none. He ran himself first leg and ended up 739th (not bad at all for a rock musician, only 2.5 minutes behind CSU's Ken Walker). Simo's girlfriend is well known elite orienteer, there has been good coaching behind this result for sure.
Second leg runner Sakari Pesola (guiter player & songwriter in "Kolmas Nainen") has been O'ing for long and he has run Jukola for over 20 times before.
Rest of the runners were less experienced orienteers and possibly not as well known except possibly third leg runner Pete Parkkonen for taking par in Finnish Idol competition.
