Most of us are under strict instructions to keep things kind of boring this week, as many of us will be doing the Chilly Half in a week.
George suggested the following option, which I think should work well:
West on College to High Park (the usual way…Souroren, Fermanaugh, etc.), then up Centre Rd. and down Colborne Lodge Road, then across to MG Trail. (That’s about 5k.)
From there, go east all the way to Coronation Park – circle Coronation Park and then head west on MG Trail. By the time you got back to Colborne and MG Trail, it’s about 15k – head straight back via Colborne Lodge, for 20k, and keep going out to Humber and beyond for 25k to 30k plus.
