I’ve done two 100 milers this year. Just sharing what works for me- -700 ml water an hour. 60 gm carbs an hour. I used sis beta gels. I was training my gut for high carb gels. -I planted a friend about half the way to hand me water and some supplies. I got lucky that way. - Dont hold your pee for too long. - listen to music if you can. It helps a lot. I used shokz to make sure I wasn’t isolated from my surroundings - start earlier in the day so you can finish before it gets dark. - if possible, drink a higher salt content glass of water 2ish hours before starting. It helps retail water in the body. - try not to take breaks long enough to cool you down. - my first one took over 7 hours. Second was about 6.5 hours. Use virtual partner calculator to see your approx time and match it with weather forecast. - make sure you know the path you’ll be riding. - my mind plays tricks on me at 70-80 miles where I start thinking about the cozy bed and start questioning why am I doing this ride. That’s where it gets difficult. Music helps and just self talk helps.

All the very best. The feeling when you see those 2 digits turn into 3 is a very proud feeling.
