Between running a luxury fashion house and being friends with the likes of Naomi Campbell and Elle Macpherson, you’d think world-renowned designer OBE would be strapped for time… Wrong.

The designer has taken on the Cycle Madagascar Challenge for Scottish charity, Enable Scotland, which supports children and adults with learning disabilities. Starting today, it involves five days of cycling along a breath-taking route through Madagascar, with Macdonald aiming to raise £100k for the charity.

ELLE has teamed up with Julien to bring you an exclusive photo diary of his trip. Follow his five-day challenge – stay tuned to see his progress.

Julien’s JustGiving page can be found at justgiving.com/julienmacdonaldobe.  You can also sponsor him by texting ESMC60 £2/£5/£10 to 10070.
