In this episode, Dan talks with Mark about trading 80-90 hour work weeks and a self-medicating lifestyle in London for the forests and lakes of northern Sweden. He shares how his father's death became a turning point, how cold water swimming became a doorway back into his body, and how a small group of friends turned a Sunday morning dip into a movement. The conversation explores trust, surrender, community, and what it means to dissolve the "thick border" between yourself and the world.Dan Allen-Hörnfeldt is Chairman of Umeå Kallbad, a community swimming and sauna association recently named one of Sweden's best places to visit in 2026, and Head of Nature for People at Rewilding Sweden. A former GB triathlete, he spent fifteen years in restaurants and pubs, winning two Michelin Bib Gourmands and twice being named London's Best Pub, before building a nationally recognised restaurant in northern Sweden with his wife. He has also competed at an elite level in open-water and ice swimming, including a podium finish at the Ice Swimming World Cup.Learn more about Dan Allen-Hörnfeldt's work:LinkedIn: https://www.linkedin.com/in/danallenhornfeldt/Umeå: https://umeakallbad.se/For more from Mark McCartney:Newsletter: https://www.whatisagood.life/Website: https://www.mmcleadership.com/LinkedIn: https://www.linkedin.com/in/mark-mccartney-14b0161b4/YouTube: https://www.youtube.com/ ⁨@whatisagoodlife3875⁩
