On Friday there were a few more cyclists in the streets than usual for this time of season.
That's because it's Winter Bike to Work Day (WBTWD), a worldwide movement where people leave their cars at home, brave the cold and pedal off to work.
It's the first edition of WBTWD in Hamilton, and some of the participants biked to a gathering in Gore Park before their commute for some hot chocolate and donuts.
Cycling advocate Johanna Bleecker was there, and explained why WBTWD is important to Hamilton.
"It shows that biking to work is a viable option for your commute – no matter the season," said Bleecker, before biking over to work in the city's east end.
The event is being celebrated by Hamiltonians and other cities around the world. Here's a few posts people shared of their chilly commute:
