Let's say you're going from point A to point B, the terrain are 50% flats and 50% moderate hills (500m max). You will be riding on the road all the time. Sun is shining, no shade in sight and the temperature is around 25°C. You should maintain average speed of at least 30km/h, and are allowed to take 15 minute break every two hours. The catch is, it's just you and your bike. No water and no snacks. You can prepare however you want before the ride, but you can't take anything with you. You can drink/eat only after ariving to the point B.

What's the longest ride you're absolutely sure you could make in these conditions?

What's the longest ride you would dare to ride like that?

Have you ever attempted to go riding without water or snacks to see how far you could get?
