Yesterday I rode 100km (Guelph to Mt Forest to the Fergus Mcdonalds). It was mostly uphill with a headwind. I don't know if I prefer flat on dirt/gravel or rolling terrain on pavement, but my legs hurt less than when I went to Millbank.

Tomorrow I'll be going about 70km to Oakville, mostly downhill with a tailwind. Easy peasy lemon squeezy.
