An ice storm hit Puslinch Tract two days ago and brought 10-30 mm of freezing rain. Decided to check out the trails today, as the temperature was around -4 °C.
Bike was equipped with studded tires in anticipation of ice.
The ponds were freezing over, but the ice was too thin to bike on. Stay off the ponds!
Double track trails were frozen and bumpy due to lots of foot prints. Near the trail head it was mostly coarse ice. Often times it felt like a long slick rock garden trail. Lots of fun but challenging as the front wheel would constantly bounce, deflect, and slide in different directions.
Single tracks trails were poor. They were covered in about an inch of hard crystallized snow. Tires sunk into the snow, even at 10 psi. As a result, the studded tires were more of a hindrance due to increased friction of plowing through the snow. Nonetheless, the single tracks were ridable.
However, the biggest issue was the number of downed trees or tree branches on the double track and single track trails. Roughly every 50 ft, and around every corner there were obstacles blocking the trails. It was hike 'n bike to the extreme!
Biking/hiking time was roughly 50/50.
