Even a 10% gradient only results in 25 metres further to roll. More fun at calculator.net/triangle-calculator.html | |

| Oct 22, 2020 at 20:56 | comment | added | Nuclear Hoagie | @Armand The idealized physics problem has the opposite result! Due to the realities of drag and friction, going down and up is less efficient on a bike. But in a frictionless "physics world", if two objects start with the same speed, one that goes down a hill and then back up will have an equal or higher speed at all times compared to one that moves over flat ground. | |

| Oct 21, 2020 at 10:35 | comment | added | Criggie♦ | If you're planning training routes, why not both? One must practice climbing and descending, and while 1% is not exactly steep its a start. | |
| Oct 21, 2020 at 10:34 | comment | added | Criggie♦ | If you're organising a TT event and planning the route, then pick the more interesting. Consider spectator access, emergency ambulance access, and risks from traffic and weather. IE if there's a lot of fallen leaves in Autumn, consider that a negative. Also consider picking the route with lower overall traffic, or whether you can get the local authority to close the road. | |
