    As opposed to the other downhill thread.

    Were you on your own or in a group?

    you should never cycle on a flat, you'll ruin your rims!!

    got up to 280kph on the auto bann 2 years ago. wouldn't say i was in a pack but there were plenty of other cars on the road at the time.

    60.5kmph on the line in a sprint into Kinsale one Saturday morning in July this year.

    The sprint point being the 50kmph speed limit sign 600m after you cross the Bandon river road bridge coming into Kinsale on the flat from the western side of town.

    How flat is flat, a road may seem flat but could have up to 1% descent which will have a great effect on overall speed. Don't think this is going to be comparable given people's different perceptions of what flat is.

    You're quite right of course Dr Colossus. A -0.5% grade makes a huge difference to speed compared with a perfectly level grade.

    My one is genuinely flat for the last km.

    It's a classic sprint point, used by many Cork based clubs on training rides. Top speed there is determined by wind direction more than anything else.

    Fastest I ever went on a flat was 35kph as I careered across the road before swan-diving onto the pavement. All this 'cos of a front wheel blowout...

    Aye, I shudder to think what'd happen if I flatted coming over Sally for example :(

    Without drafting, I reckon I've been up to about 52-54kph or so on the track

    That puts me about 215kph slower than Fred Rompelberg, but he did have the benefit of drafting a dragster:

    I reckon she'd get quite angry.

    Just checked.........according to my Garmin, the fastest I've ever gone was 73456.8976 km/hr although it wasn't on the flat - it was while descending from sea-level to -1756m in 10m of horizontal distance!!

    in the real world - just over 54km/hr on the coast road from Bettystown to Mornington.

    Similiar, nice cycle/stretch of road along there.

    Yep. Those old abandoned mineshafts are a bugger. Hope Lassie was able to bring help... ;)

    Probably when things are being wound up at the end of a race. But I wouldn't be looking at my computer.

    :-D

    Fastest i ever did on flat was ironically almost exactly the same as downhill. Approx 50mph
    I was drafting something pretty large :)
    But the wind blast when i could no longer keep with it was fairly strong.

    Thats nothing though, check out this Fred, :) Literally :)

    Something like 51km/h going along from the Burlington to Donnybrook, but I didn't keep it very long. I've tried to do it with out success every morning since.

    88kmph on the flat on a newly tarred road in france, while making a break from a group! on my cycle comp the gradient was registered as -0.05% there was a slight tail wind but nothing worth!!
