5km to 50km at 50 – Surviving Your First Ultramarathon



An in-person talk at Lloyd’s from Thrive4Life
It’s never too late to start running… ultramarathons!
Join Martin Anderson for an inspiring lunchtime talk as he shares the highs, lows, and unforgettable moments of completing his first ultramarathon at 50.
From hill training and sleepless nights to staying fuelled and avoiding ‘the bonk’, Martin offers a relatable glimpse into what it takes to tackle the ultra-distance challenge. Discover the mindset that keeps ultra runners moving, the difference between pain and injury, and the unexpected joy found in simple things like cheese sandwiches and dry socks.
Whether you’re dreaming of your first 5k or curious about pushing beyond a marathon, this is your chance to get inspired by what perseverance and preparation can achieve.
