I ran the Frolic this morning and it’s now covered in water and light snow. I’d consider most of the loop runnable if you don’t mind having wet feet for the full duration. The only part I found tricky was the rocky uphill from Cortright Road to the crossroads (4-way trail intersection). The rest is slow going but doable.
I wasn’t too thrilled about running this in the snow today, but the run gave me 10 or more completions on all 10 Challenge courses. I didn’t want to wait on this one since it will probably only get worse.
