Here's a worked exmaple using your figures:
Average Flat Pace:
3 mins/km (1000/2000 * 6)
Uphill Adjustment:
+25m ascent = 1000/1450 * 6 / = 4.14 mins/km
equivalent to 4.14-3 = +1.14 mins on flat
equivalent to 1.14/3 = 0.38km of extra flat distance per 25m of ascent
so, 0.38km / 25 = +0.0152km per 1m of ascent = +15.2m per 1m of ascent (0.0152*1000)
Downhill Adjustment:
+60m descent = 1000/3640 * 6 / = 1.65 mins/km
equivalent to 1.65-3 = -1.35 mins on flat
equivalent to -1.35/3 = -0.45km of less flat distance per 60m of descent
so, -0.45km / 60 = -0.0075km per 1m of ascent = -7.5m per 1m of descent (-0.0075*1000)

Please assist me on how to calculate the impact (Every 1m (up) is equivalent to +xx.xxm) of hills and downhills on my mountain bike ride based on historic data.
On my avg flat speed , I cover 2000m in 6 min
Uphill with a 25 meter climb I cover 1450 m in 6 min
Downhill witch a 64m decend, I cover 3640 m in 6 min
Kindly show the calculation and how you enter this into the Adjustment for hills sliders

Hi John
Sorry you are right. That's because I was using it on different PCs I think

Hi Pierre - the Timer Settings should be saved automatically on the device you are using. Is this not happening for you?

Hello
It would be ice to keep the settings for a particular user from one login ot another one

Thanks very much John - that's brilliant! It even seems pretty much OK for my Etape 2015 if I use +30. All users need to do now is find out what settings work for them for different styles of riding - then apply them accordingly. (hmmm - user presets? - save settings by name, select named preset from dropdown... maybe too complex for users)
One minor thing - the new timer settings window doesn't appear in the View for this route: https://www.plotaroute.com/route/184952
(although it is OK in the Edit window for this route)
It's fine for my other routes.
Great to have this in the Edit window - much easier to analyse what's happening.

The timer setting ranges have been extended now and the bike defaults adjusted. We've also added the fine tune +/- buttons as well to the hill adjustment settings.
You'll also probably notice a new link to the Timer feature we've added in the route planner, just under the distance counter.

Thanks John
I think 27kph is a bit fast for average flat - 25 kph would maybe suit more riders - tourers and mediocre rodies (like me)
I like the +19 of course
Descents don't normally account for a large % of a ride so I siuppose they are less important - I get a wide range of values (eg on a recent ride -2.5 to -5) so the -6.15 could be OK (why not -6.0?)

I'll see if we can change the timer ranges and defaults quite soon. It sounds like the following settings for cycling are being suggested:
Avg Flat Speed: Change default from 20 kph to 27 kph (current range 1-40 kph is OK)
Uphill adjustment: Change default to +19m distance for each 1m of ascent (increase range to 0-30)
Downhill adjustment: Leave default of -6.15m distance for each 1m of descent (increase range to 0-30)
Steep downhill adjustment: Leave default of -4.1m distance for each 1m of steep descent (current range -10 to +10 is OK)
If anyone has any views on these settings or can help by testing them out please post back here.
Thanks,
John

Thanks John - I take the point about sampling - I think it really isn't a problem as long as the site uses a consistent method. It is obviously really difficult to do this perfectly accurately and is bound to miss features that might make for hard work for a cyclist: imageing cycling over a continuous series of 1m humps every 10m for 1km - this is a 100m climb that can't feature.
The range extension would be useful (and - & + buttons please too) - thanks.
