Cycling shorts are a must and gel seat, warm sleeping bag for the desert and warm clothes as it gets very cold at night, (all depends on when you are travelling).
If you don't like meze, lamb or pitta bread then you need to supplement your food somehow, I loved the food but others may not, energy bars and chocolate might be a good idea to bring.
You need at least £250 for food, tips and the daily lunch kitty, boat trip and night visit to Petra whilst away, its expensive but you don't need money for much else really unless you want camel rides etc.
I would like to have seen a cycle guide at the back of the group as well as at the front as one day we did have a bit of a mix up with directions and the support vehicle had to leave us to catch the other cyclists who had taken the wrong turn.
The support vehicles needed more repair kits on board as we had four punctures in one day and not enough repair kits this meant one of us had to finish the day on the support coach.
Would have liked a larger vehicle for the longer parts of the journey by coach as it was quite cramped with all our stuff and didn't make for a comfortable ride.
Quite a few of us had upset stomachs at some stage in the trip, nothing too bad but its worth a few supplies to help.
