Usually I run down the crown of the road and move to the sides when cars approach.
This is what I do and is why I tend to prefer running on quiet neighborhood/country roads.
Now the two weeks leading to the race are a complete bust. I've never believed in long, deep tapers, preferring a modest reduction in volumn with a corresponding increase in intensity over the last 10 days. If the injury is healed by next Sunday how much impact will this huge, forced, “taper” have on my race plan? I'm an experienced marathoner; I've raced 12 in the past 10 years. I'm not new to the distance, but new to taking this much time off.
What have you been doing for recovery other than rest? At this point in the phase, all the m-s stuff is basically completed, so cross-training for similar duration and intensity to the planned runs should be enough to prevent peaking early. Given the nature of the injury, pool running might be best though the elliptical trainer/nordicski/rowing machine could also work as ways to mix up the routine 2-3 times per week. As long as you replicate the stress on your c-v system then you should be good to roll into your usual taper routine. Does that make sense?
