The Endurance Athlete's Setback Protocol: Illness, Injury and the Smart Comeback

If you train seriously for triathlon, running or cycling, you will get sick, and you will get hurt. Most athletes handle it badly. They push through a cold because they hate losing fitness. They ignore a niggle because they're riding a good block. Then a three-day problem becomes a three-week one, or a sore hip becomes a stress fracture. The anxiety about lost training does more damage than the break itself. This guide gives you a clear protocol for those moments. You'll learn how to decide when to stop, how long to take off when you're ill, and how to tell a normal niggle from a warning sign. You'll learn how load and under-fueling combine to cause bone stress injuries, and how to build a recovery plan you can follow. You'll also learn how to protect your head while you're sidelined, and how to return in stages without undoing the work. It's written by Harry Palmer, a professional triathlete and coach. In 2026 he was diagnosed with a stress response in his femoral neck, which ended his season before Ironman Wales. He had ignored hip pain for around five to six weeks during a heatwave, when his appetite dropped and his training load climbed. He has also made the mistake of training through illness and paid for it. Harry sees these problems as an athlete and as a coach, and he writes from both sides. He shares what he got wrong, what he's doing differently, and how he's approaching his own return, which includes MRI follow-ups, a walk-jog program and a carefully managed first long ride. This is not medical advice. It's a practical, honest framework from someone who is living it.
