OK, so there had to be one leg which was less than inpiring and basically gets you from A to B, and this is it.
Original plan was to head into Nokomai and the headwaters of the mighty Mataura River. A nice ride but it would turn the middle of your Brevet into a real test of endurance and stamina with little more than two pubs to stock up on food/supplies for almost 300kms of serious riding.
The solution was to pound the pavement to Lumsden (pop 453) and some welcome shops and accomodation. Can't guarantee all food options will be available in the small Southland town but you should fair better than just the Garsten and Waikaia Pubs (although these are both worth a visit).
After leaving Lumsden it is a gentle stroll through rolling Southland countryside before heading up into the Waikaia Valley.
