Miller will complete his final marathon in his home city today, capping off a year-long odyssey that has taken him to every continent.

The 33-year-old is expected to receive a hero's welcome when he rounds off his adventure at Albert Park Lake, in the RunLikeCrazy Marathon, organised in his honour. The gutsy fitness fanatic has braved illness, injury and permanent jetlag to conquer 52 marathons in 52 weeks across the world, raising about $15,000 for UNICEF and Facing Africa in the process.
