We have these CRAZY psycho bugs here that are very territorial and actually chase you when you run down the road which drives me crazy in the summer, spring and fall, but in the winter these buggers (pun intended) are no where to be found, so I'm less worried about them harassing my baby. So I can bundle a baby in a snowsuit (or two - yes Lillian was in 2 snow suits on that -12 degree run) and run off with no ugs buzzing around her head.
I run on a lot of country roads, which are usually dirt roads, so ice usually isn't a big issue for me. My jogging stroller provides extra support when things get a little icy. As for the nasty slush and snow, even when we have a few centimetres on the ground (or several for that matter) my baby jogger can get through it no problem.
