The Trek-Segafredo rider announced the decision via Twitter today.
Been thinking long and hard about Rio and I've decided to take myself out of the selection. Long season ahead. Best of luck Team Canada!!— Ryder Hesjedal (@ryder_hesjedal) June 3, 2016
His announcement follows one by Tejay van Garderen (BMC), who cited concerns for his pregnant wife because of the Zika virus outbreak in Brazil as his reason for pulling his name from consideration for the USA team.
Hesjedal competed in the last three Olympic Games - in London and Beijing on the road, and at Athens 2004 in mountain bike cross country.
