London Landmarks Half Marathon In April 2026, I’ll be running the London Landmarks Half Marathon in support of Dementia UK—a charity that supports families affected by dementia.This isn’t just a fitness goal for me. It’s personal. Both sides of my wife’s family have recently been affected by dementia. We’ve seen first-hand the heartbreak it causes—loved ones becoming confused, scared, and forgetting even the people closest to them. It’s hard to watch, and harder still to feel helpless.
