Riding safari experience I have none of, getting over broken bones from crashing bikes I'm very familiar with...one thing I have learnt is don't rush it or try and over do it. The body is amazing at repairing its self...things can look a whole lot better in 4-6 weeks.
On a positive note: getting past this set-back could give you that extra bit of mental preparation to help on the tough Dakar stages and get you over the finish line!
We're all behind you Jaybo and praying for your speedy recovery!
All the best
