Sorry, but looks like neither mfw or "the table" will accept anything less!

Just glad I started slow...

16:39 up Mt P!!! Yeah right. Even onbike couldn't manage that last year

1 Sumner (Heberden Av) to Evans pass (summit rd), 2.0km, 206m
2 Lyttleton (police station) to Evans pass (summit rd), 3.4km, 256m

Hey mfw, I don't get this variance in altitude gain. Surely the climb from Lyttleton to Evans isn't 50m more than Sumner to Evans, particularly given the Police Station is already elevated?

What do you make of this?

My map software say the start in Sumner is around 15m and the start at the copper station is around 25m. And Evans summit is about 193.

maybe it's total climbing and there's a downhill bit one side we've never noticed

I'm gonna have to go ride the bays with a the gps now

And a stop watch!

1 Sumner (Heberden Av) to Evans pass (summit rd), 2.0km, 178m
2 Lyttleton (police station) to Evans pass (summit rd), 3.4km, 168m

So the above would be closer to the truth then.

That actually sounds about right to me .. I raked back through all my rides with my Garmin and roughly the same ...
Sumer to Evans 180 - 183 vert metres and 2.04 - 2.06 km distance
Lyttleto to Evans 171 - 173 vert metres and 3.3 - 3.32 km distance

That was over 6 recorded passes up Lyttleton to Evans and 4 from Sumner to Evans, but very few were at a speed worth mentioning ... .

Yep, the 'par' times are just a table of averages, so are very volatile at this stage with so few numbers in, and some crazy targets for anyone sill enough to enter the board with a competitive time at this point in the season

The fact that mapmyride is a crappy way to measure climb profiles for climbs of this size But it's the best we've got! However, if you GPS enabled guys have got some real stats, feed them to me and I'll replace the mapmyride ones
BTW: How does the GPS handle accumulated climbing through rolling hills, like through the bays, does it smooth out the bumps and come out with artificially low ascent values?

Garmin has total ascent and total descent values..

So what are you saying Martin .... you want those of us with GPS's to ride up these climbs serval times so we can gain accurate stats on metres climbed and length of climb .. sounds like fun to me .. If only I could get the time.....

No they don't smooth out the bumps, it just accumalates, eg from last weekends ride
SOK to Lyttleton total ascent 122m total descent 433m
Evans to base of Major Atkin total ascent 74m total descent 260m

The accumulation does however depend on how frequently the GPS is talking to the satellites. E.g. if it is only recording every 10 seconds and you dive down into Rapaki Bay and are 20m up the other side before the next reading then it will not take the true descent into account. It also depends on how accurate the vertical is recorded. Altitude (z) is typically not as accurate as easting (x) and northing (y) with GPS due to the triangulation between the GPS unit and the satellites. But some units use barometric instead of or as well as GPS for altitude readings.

Another consistant effort from Noel

Now what's the forecast for tommorow morning... 5 degrees, rain and 36kph SSW winds, I think the Mazda is sounding more appealing than the Morrie at this point...

I'm gonna open up my account with some big numbers

Dyers 22:19

Bstd 20:45

First climb for me today. Sumner to Evans: 9.11
Pretty dissapointed with that time though. Just had new cables put on my bike which had stretched giving me very limited gears for the climb. Wasn't able to spin at any point.
I was going to do the Evans - Broadleaf but sheets of ice across the road at the bottom of that climb put me off... Alright going up but coming down those descents on Summit rd, just a bit too dodgy.. I'll get that climb in another day when i have a full range of gears..

Here we go again.

3. 18 50'

4. 15 15'

Thanks
