Just got on the thread. Good luck and sorry to hear about your foot.
I raced Dakar last year after breaking my leg at Morocco, so I only had 9 weeks recovery. That meant that I didn't ride my bike at all from the day of the fall to the start of the race. I felt great through the first 2 stages but didn't manage to finish the 3rd although I beleive it was more to do with lack of experience than the break so I know you will do well. Just make sure you keep up the fitness!!
