What amount of ascent for a 'flat' 10 mile route?

guttertrash

I know I've seen a thread about the amount of climbing over a distance that would class it as hilly, but at the moment I want the opposite. Over a 10 mile route, what would be the max amount of ascent for it to remain 'flat' in your opinion?

In my head, it would depend on how steep they were, lots of rolling hills you can normally keep a good speed over as the momentum gained gets you up the next hill.

Theres no such thing as a rolling hill in North Derbyshire

I'll believe that! I, however, live in Cambridge where there is no such thing as a hill.

i reckon a flat 10 mile route would be about 50m of climb and 100m would be verging on rolling terrain,if you want flat go to the fens it dont get flatter than that, on a ride there i registered no climb at all for a 20 mile stretch.

How far north? The A6 is pretty flat from Bakewell southbound

Chesterfield, so whichever way I go there is a hill.

Hi folks.

I though a 'flat' TT course consisted of a downhill ski-ramp start onto a dual carriageway, followed by a grand total of minus something feet of climbing?

My 'flat' 22 miler that I regularly do involves about 840ft of ascending (according to my garmin) if thats any help?

Flat enough so that any segment done in either the inbound or outbound direction would have essentially the same power-speed relationship.

I bike all around east yorkshire where there are hills, rolling hills and plenty of flats, on a weekend i stay at tibhslf and do a 20-40 mile loop and i cannot find any flats anywhere!..it kills me.
When i do a flat 10 at home i prob do 30-100ft of climbing.

its gotta be tough to train for flat TT's around here...

Am sure if you looked you'd find hills in East Yorkshire, it's not that big, round the humber it's flat.

This is as flat as I've done locally.
