Collingwood's first to fourth year players returned to the Holden Centre on Monday to partake in an annual two kilometre time trial. 

Fresh from their off-season breaks, a group of players overcame 34-degree heat to put their running and endurance skills to the test. 

Midfielder Jack Crisp crossed the line in first position, while Tim Golds, Tim Broomhead, Jamie Elliott were also among the most impressive performers.
