Don't know how many of us can remember our First ride.

Mine was on a flat route and was a family concern with a group I knew. 20 kids and their parents. 28 miles were done and there was only one hill. 200 yards at about 5% slope. All the kids made it but only half of the adults. Turns out that one of the parents that did not make it was a soccer player for the town club. He can run around for 90 minutes on a football field and reckoned he was fit. But the one hill on a flat run and he was cooked.

I live in a hilly area and they are part of the rides. Doesn't matter how fit you are- If you do not do slopes- then you will struggle. But listening to others reports on Flat rides-Think I might struggle to stay with the pack.
