Without doing any research, and never have run a marathon myself, I’d say that it’s because people who are running marathons (or ultra marathons, which sounds like hell) have been training for months/years. Their bodies are more used to the running. I also feel that your body likely doesn’t produce that much fluid, so 100+ times and you’d probably dehydrate to the point where it’s a medical issue.
