Including bike?

$3000-4000 depending on how you cut it. Other people will be more/less expensive depending on their airline tickets, how often they bivvy vs. hotel, how fast they ride it - faster riders might have more expensive kit but they will be riding/eating for fewer days and possibly using fewer hotel stops. Short answer: no idea, but probably pretty expensive for me.

Including bike?
Yeah. Rough breakdown:
Flights £850 plus £150 to change the return flight date (British Airways, LHR > YYC, PHX > LHR)
Food, Lodging and Mechanicals en route: £1600
Extraction from Antelope Wells to Phoenix £400 (shuttle ride, and cousins hiring car for a few days).
Bike, bags, dynamo kit, etc £3000ishWorlds most expensive free race.
