This week, Sam & Katie chat with up-and-coming triathlete Jack Caldwell.
Hailing from Eden on the Far South Coast of NSW, Jack has been training from a young age. A naturally strong swimmer who also shone in school cross country, Jack eventually combined both strengths—adding cycling into the mix—to discover his talent in triathlon.
After playing a range of sports growing up, Jack began racing Sprint Triathlons throughout high school. Earlier this year, he claimed the Men’s Junior Title for the Oceania Region in Devonport—clocking a blistering 15:15 5K off the bike. He also boasts a 14:56 PB from a Sydney workout, and fondly recalls defending his Panboola Wetlands parkrun course record.
Jack was all set for World Tri in Wollongong, but a pair of stress fractures and other setbacks have forced some recovery time. He’s now building back gradually, with eyes on moving to the Gold Coast in 2026 to train full-time.
🏋️♀️ Training Weeks
Katie hits 3 x 1K off 90s (3:20 splits) plus some 400s off a 200 float. She’s taking a weekend off with suspected iron deficiency, rounding out at 63 km for the week.
Sam clocks 43 km running across four sessions and 105 km cycling on the off days.
Jack shares a look at a massive training week from when he was fit—30 hours total, including 30 km swimming, 63 km running, a 5K PB, plus gym and cycling.
