The Leopard Trek team announced it would leave the Giro d’Italia tonight, following the tragic death of Wouter Weylandt in a crash on stage 3.
"Leopard Trek was allowed to cross the line first in memory of their fallen teammate Wouter Weylandt. The team completed the neutralised fourth stage today, with the team's eight riders crossing the line, arm in arm ahead of the field, along with Weylandt's close friend Tyler Farrar of Garmin-Cervelo."
The stage was "neutralized," meaning everyone rode at a steady, uniform pace as opposed to competitive racing; each team took a turn leading the race, and all riders slowed and fell back to allow the Leopard Trek team to ride ahead and cross the line first, in tribute to their fallen teammate.
I'm pretty sure this doesn't happen in any other sport.
