I was walking along a stretch of my favourite canal path about a month ago with the barking machine and my good friend, documentary photographer Giles Penfound, when we encountered Dale Thomas running toward us. Usually, runners are reasonably head-down and on a mission, except Dale wasn’t.

He wore a running top promoting the Ollie Young Foundation and was happy to stop briefly to talk about the cause. What came from our ten-minute chat convinced me that he had several human stories to share. And while he’s not a photographer, Dale is certainly an encounter, and I’m always championing encounters as those magic, serendipitous moments where we connect, maybe make a portrait, and talk about life.

So, Dale is today’s guest, with a story about community, a race across the desert that, in many ways, saved his life, and an outlook shaped not by medals or miles, but by a belief that life is for living, fully, curiously, and with your family never far from your heart.

Also from the mailbag, Johann van der Walt, artisan camera bag maker and, frankly, my new best friend, and like London buses, another Johan appears! Johan Rispling is here to ask whether photographers are secretly moonlighting as painters, poets, or pianists, and Andrew Scriven checks in from Andalusia via Covent Garden.

Links to all guests and features will be on the show page, my sincere thanks to Arthelper, who sponsor this show, plus our Extra Milers, without whom we wouldn't be walking each week.
