You can change your travel option by logging in to our registration portal, and then clicking My Bookings > Bookings.
From there, you'll be able to view the bookings you've made, and edit them as you wish. To change your travel option, hit the Edit button on the right-hand side. Options you can change include switching between 'with flights' and 'without flights' options, adding or removing extension trips, and changing your fundraising option.
Please note that once the registration portals are closed to new bookings (31st January 2018 for overseas treks, 16 weeks before departure for marathons), changing your travel option will incur a fee of £100+ any non-recoverable costs to us. See our Terms & Conditions for full details.
