Top effort.

Some of you guys must live at the base of some big hills.

86km and 1954m this morning. Wasn't feeling 100% so it was a bit of a grind.

I do live q few kays out from a few fairly decent climbs, but 10km of that ride was along the flats to get to the first climb :)

Did the Strava challenge yesterday also. 164km but only 1775m of up :oops: Did 85kms in the hills and around 80 on the flat. Wanted more climbing but it was an average of 35 degrees down here in Adelaide - Garmin registered 40+ on the road for quite a while. That, plus I had 340 odd metres of climbing in the legs from the day before - running, not riding - up Kensi Road to the lookout and over the trail to Coach, tough on a bike, even tougher on foot! :shock:

Completed the Strava Quarq Challenge on Saturday. Uploaded the 162km with 1650m of climbing, then did the correct elevation thing in strava and it dropped to 1100m. :(

Huh, I did the correct elevation thing on Sat too and gained 900m :-) Unfortunately, statmonkey had already fetched the previous elevation gain..

Is this elevation correction something that Strava does automatically as it processes one's mobile data? Then sends the corrected data back out to the mobile device? When I get back from a ride, I get out my iPhone and hit save, then by the time I go inside after putting things away, the distance has usually shrunk by a small amount (a couple of tenths of a km out of say 30 or 50km) but the climbing elevation gain has in some cases almost doubled. It is then usually a fair bit more than bikeroutetoaster but a small amount less than ridewithGPS.

My experience with iPhone is similar to toolonglegs.
On the device it exaggerates elevation, when corrected by Strava I consistently get 10 - 20% below real.

Just out of curiosity, I corrected the Garmin data from my Sunday ride. I was expecting a modest drop in meters climbed... but 1954m jumped to 2491m?!?

Which measure is correct. I assume everyone on here isn't correcting their data, or are they?

I didn't know there was a correct function. I have noticed though sometimes when you hit the save button and it downloads you get a set of figures and then when you look back later the numbers, usually the elevation, is revised, usually down. Stuffed if I know, I just go with what it says knowing it's not truly accurate but it probably averages out over the year.

I've found that I get positive inflation through the correct elevation feature when doing specific steep climbing. Whereas flat rides always get corrected down.

Edit: when using the garmin

I never use the data correction.

If you log in to Garmin Connect you read up on the elevation correction and how it works - not sure what Strava does with theirs but I guess it is similar. It essentially uses known altitude measurements based on mapping data AFAIK. This is why there are always differences in elevation when using things like mapmyride, ridewithgps etc. to plot potential routes.

The Edge 500 has a barometric altimeter which *should* be giving the most accurate elevation readings based on exactly which path you have taken on the road. As long as your starting elevation point is correct, then everything will be fine. Although if it isn't, the +/- over a ride should still be the same.

EDIT: Strava also does funny things with moving time/elapsed time - the figures are never the same as what Garmin Connect displays which is just the raw data from the device. Strava has their own algorithms which do funky things.

I don't think strava (via iphone in this case) handles stops in rides all that well either. always seems to be a lag with extra time added. Anyhoo on with the climbing. :twisted:

It has stopped so I will get an after work recovery run up Mt Lofty. :D

I'm going to get up extra early tomorrow and get some big numbers in before work, hopefully.

I'm coming second or third, but 20,000 off Daccordi. Hahahaha.

We should arrange a local climbing fest - any other Adelaide BNA members keen?

I'm keen - earlier start the better, and I'm keen to do any sealed climb anywhere in Adelaide as long as the descent isn't too hairy.

I don't like Coach Rd or Kensi Rd - both give me the heebee geebees coming back down.

I really, really want to hit 3000m in under 100km. Without the aid of Strava elevation correction of course!

Tomorrow morning I think I'm going to try and go for a ride with a crew that head up to Lofty on Tuesday mornings, 550am at the lights, after that I want to do a repeat on Coachhouse/Woodlands... not sure if the repeat will eventuate haha.

i'd be keen. Maybe one day at Easter could work. I did a Mini Alpine course with the Audax guys a few years ago that was good. Don't know the elevation but
Mt Osmond (Beaumont side), Freeway to very top of Lofty, down to Windy Point, up Towards Crafers via Sturt Valley Rd. Into Stirling for a refuel. Down Freeway, back over Mt Osmond and up Greenhill, down to the Parade for the end point. 100km.

Or there was the Dirty Dozen route Adelaide Cyclists did that I missed, we could find that.

Dirty dozen does Kensi & Coach... I'd do Coach again if I had to, definitely never going near Kensington again. It's way too narrow and car filled and suburban for the speeds you can catch heading down.

I'd be keen for a Dirty Dozen style ride, though. There are plenty of roads you could substitute Coach and Kensi with... Osmond (Beaumont side) comes to mind, I like that climb a lot.

Sounds like a plan. Around Easter works for me. I'll be back running a compact by then :lol: and I've got a week off work.

Let's pencil it in.

I'm not the fastest climber out there but I like to think I can hold my own, so happy to be challenged whatever route is determined. My resolution for this year was to explore more roads/climbs which so far is working out, the only limitation is spare time to get out there!

I'm in the same boat as you I think. Not super fast - haven't been riding for long enough - but I haven't had a climb beat me yet and I think I've ticked off most of the tough climbs in the eastern and north eastern climbs.

We should trade strava deets

Ok gents lets go for Easter Friday. I will put a bit of thought into a route that gives us around 3000m and post it up for comments.
