I have a trio of guests on the show this week. Photographer, author and adventurer David duChemin joins me ahead of his full appearance next week for a shorter but powerful conversation that weaves through some of the themes we've explored on the show over the past year: presence, obsession, talent, adversity, courage, comparison, and yes, that old imposter syndrome chestnut, all with David's signature warmth and insight.

My good friend, documentary photographer Giles Penfound, joins me for a walk and shares a disarming way to connect with people you might never normally speak to. If you've ever felt that knot-in-the-stomach hesitation when approaching a stranger and asking, "Can I make your portrait?", Giles might just have the key to making those conversations feel not only possible but natural, and Valérie Jardin returns for this month's Teach Me Street, ahead of our summer recording in Paris.

From the mailbag and also on the show, Robin Chun reckons he's made his picture of the year, William Leonard's been having camera bag nightmares, Paul Moore's in a derelict hospital shooting for a client while listening to our supernatural episode, and I've a story to share about how homelessness led to a walk… which led to a book… which has now become a film, out next week. If you know the story already, I hope you won't mind the revisit. It's a path worth walking again.

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.
