My (bike and ferry) commute is very short these days and I am using my Brompton. So I am getting up at dawn for a 4 mile run every day. I do a couple of proper rides on the weekend, both for speed rather than distance. My legs are feeling much better now and I am really enjoying the running, and so far I have seen coyote, deer, skunks, owls and hawks as well as all the smaller things. To add to the cross-training, I am also doing some canoeing again, which is fabulous.
