Bright sunny day, blue skies, and below freezing temperatures (-3 °C). With nice weather like this, I could not resist a quick afternoon bike ride at Puslinch Tract!
Primary route was the pines single track, and the trails were very good. The snow was a bit soft, but has been packed into a 15 cm wide trail. It was around 1 cm deep. Veering off the packed snow trails was also okay in most locations as the snow was less than 2 cm deep. However, in a few low-lying and snow drift areas, there was still 5-10 cm of snow covering the trail. Even then, it has been lightly packed and flotation was still possible. Extra effort in pedaling was still required though. Nonetheless, the pace was still brisk. Both small and medium hills were climbable as the snow was packed and less than 1 cm deep. Traction was not an issues, and there was no ice to be seen. In the end, the pine trails were very good and they were all ridable.
The double track snow trails were also great. They've been heavily packed down nicely by all the trail walkers. Snow was a little wet and at most 1-2 cm deep. No ice. Pace was fast and steady.
Parking lot and entrance were muddy as heavy machinery (construction) has cleared the snow. As a result the ground was exposed to direct sunlight. Other than carrying the bike a couple of meters past the entrance, both the single track and double track trails were covered in snow.
Bike was equipped with knobby tires (2.5" front and 2.1" rear) at 15 psi.
