Canberra’s Hill Climb Guide

Welcome to my King of the Mountains V2.0, now with improved elevation calculations thanks to some good folk on the Vikings cycling forums I discovered how extract the data from Garmin TCX files so I could graph the actual data and not rely on the rather clumsy screen grabs. In addition I have used Tableau to graph the data, which allows you to select and compare only the climbs you are interested in. This is still a work in progress so any comment on the Tableau graphs is welcome. All the graphs can be viewed in greater detail by clicking on them which will take them to full screen mode.

The max gradient should be taken with a bit of caution, although it was calculated from the data because of the sometimes erratic nature of the Garmin edge units some of these calculations are a little random.

Firstly here are all the climbs on the one graph, noting that Groggins and Charlottes Pass do continue on for some distance but I’ve cut them short here to ensure you can still make out the other climbs.

Cat X– The big ones to really test you.

Corin Dam – This climb has two distinct parts. The first starts at the turn off to Corin Dam on Paddy River road up to the gates at Woods Reserve. The first part of the ride is easy with fairly low gradient. From the gates to summit the ride gets harder as gradient increases and is what makes Corin a really good climb.

Honeysuckle Creek – Also known as Apollo Rd South of Tharwa. The start of this climb was measured from the bridge about 2km from the Nass rd / Apollo rd junction. This is one of hardest rides in Canberra in my opinion with some short sections hitting a 20% gradient.

Groggins and Charlotte’s Pass – are both located South of Canberra in the ski fields around Thredbo. The data for these climbs was given to me so I can’t comment on the climbs but I hope one day to get there. The Charlottes Pass ride goes on for 32km and there is a bit more of a climb but by the 25k mark you’ll have broken the back of this climb.

Cat A – Represent some of the “bigger” challenges around Canberra, these are usually the ones with the killer gradients.

Black Mountain (Telstra Tower) – The climb was measured from the turn off to the very top of the summit, past the car park entry where a lot of riders usually stop their timers. Black Mountain in my opinion along with Fitz’s Hill represents one of harder climbs in Canberra. What makes it difficult is the first 400 metres, which has quite a hard gradient of around 15%.

Mount Ainslie – Preceding the climb to Mount Ainslie is the climb at the Australian War Memorial which adds another 34 metres to the climb.

Mount Majura Our famous secret climb. This was measured from the turn off on Majura Road, not bad considering there is a additional 81 metre  up Federal Hwy (See the Cat C Climbs) before you get there. At about 600m there is an entry gate you’ll have climb over to continue the climb.

Fitz’s Challenge – measured from the half moon creek bridge to the KOM line at the summit. This is without a doubt a brute of a climb. While average gradient for this climbs is just over 10% in reality because of a dip in the climb most of the time you will be facing a gradient of 12 to 13%
Note I’m currently missing the data for this in version 2 but hope to have it soon

Cat B – These represent good training climbs (well for me at least) that wont  leave your legs screaming when you reach to the summit.

Red Hill Measured from the turn off to Red Hill. Reported gradient on the chart above probably doesn’t do Red Hill justice. In measuring the distance I measured to the summit which is at the restaurant but you can see from the image above the climb plateaus at around 1.1 km where the main lookout is. If measure the gradient to this part of the climb it comes out at around 9%, on par with Black Mountain, just shorter. Maybe not one of the beginner hills.

The Three Sisters – This is the climb out of Uriarra crossing heading back to Mt Stromlo. Measured from the bridge crossing to the KOM marking on the road. So called because of the three distinctive sections to this ride. Always fun at the end of a race, which happens frequently.

Mt McDonald – Located on the other side of cotter and goes up around cotter dam. Measured from the turn off on Cotter Road to the KOM marking on the road. Good training ride, not difficult, just a good consistent gradient.

Old Federal Hwy – This climb is located in the Yass Valley just past Sutton. Instead of going up the Federal hwy there is a turn off at the nursery which is the old federal hwy. The climb was measured from the bridge crossing the Yass river to the summit. As shown it is on par with Mt Stromlo

Mt Stromlo – Measured from the turn off on Cotter Rd to very summit which means going up the small road which is in average condition near the new observatory.  What I like about Mt Stomlo is the even gradient for the climb. Nothing challenging but a can be a good workout if you choose to push yourself.

Pierce’s Creek – This is the first climb after Cotter Dam on Paddy River Road on the way out to the tracking station. At 9% it is a toughy but relatively short.

Monaro Hwy, Theodore – This is climb as you leave Canberra on the way to Cooma. Nothing spectacular about this climb other than it has consistent gradient.

Old Cooma Road – Good climb with some steep sections on it. This road can get some traffic with the trucks going to the quarry.

Smith’s Gap – out at Bundgendore might be short but has a high average  gradient of almost 9%

Erindale Road – You’ll note the graph for this one appears quite “grainy” compared to the others. This is because it was actually mapped going down the hill and the higher speed meant there were less data points to graph.

Wallaroo – Good solid climb with some steep sections in it.

Kings Hwy, Queanbeyan – only advice here is get in quick if you want to do this one, they are currently redoing this section of the Kings hwy and it will be shorter and lower soon.

Cat C – I guess these can be classed as the beginner climbs but should not be underestimated.

Australian War Memorial (AWM) – Normally I don’t map climbs this small but as this is the lead into Mt Ainslie I thought it was good to have here. It’s s short climb but does peak at 8% and is a nice way to way to warm up before the big climb to Mt Ainslie.

Mt Pleasant -  Measured from the turn off on Fairbairn Ave into Duntroon. One of my favourite training rides. Starts of with a kick on the first section but then evens out to consistent climb.

Coppins Crossing - Measured from the crossing to the summit.

Federal Hwy, Watson – Starting from the last roundabout leaving Canberra, starts of easy, nice consistent gradient, smooth road. Importantly this is the lead up to the Mt Majura climb.

Googong Dam – Short climb but steep also it is a dead road making it a tough climb in its category

Stockdill Drv (Poo Hill) – so named because it is the road leading to the Sewage plant, the smell alone should be enough of an incentive to do this climb quickly.

Uriarra Crossing West– This is the climb opposite to the 3 sisters at Uriarra Crossing. It is a little below par but given it is part of the Uriarra loop, it a frequent climb and therefore people might like to know about it.

Tidbinbilla – On the road to the tracking station. Not to hard unless it is on the finish to a race at the tracking station.

 

Techie Notes

An interesting point came up while preparing the data for this post. You’ll notice that on some of the climbs the data points are a lot closer than others. For example in the Cat C climbs Urriarra West compared to most of the others. The difference can be attributed to the use of the new Garmin Edge 500 which appears to record data points more frequently than the 705. I guess this one of those less obvious feature improvements you get with the 500.

It should also be noted that while Garmin say their devices are accurate I have found on given day I can get up to a 10% variation on the reading for the climbs so if you’ve recorded these climbs as well but have a different elevation just bear this in mind. In fact you’ll notice with my Corin and Mt Majura recordings there are some odd spikes in the data which I just put down to these glitches.

For those interested I’m planning to write a follow up article on how I extracted and manipulated the data.

 

 

If there are any other climbs that should be included please let me know.

The Garmin Edge series 305, 705 and 500

This is not meant to be a thorough review of the Garmin Edge series, if you want specific reviews there are plenty of them out there and you can compare the specifications directly on the Garmin website. What you will find here is images of all three units side by side so you can see the size difference and get my valuable insights into the little gotchas with the each unit.

DSC_0117

Garmin Edge 305

  • Reasonable size compared to the 705, smaller than the 705 and still looks reasonable when mounted on your handle bars 
  • It does have limited navigational ability, to be honest not something I ever used  and it is too limited to provide effective navigation if you are touring.
  • File format, because the 305 uses the TCX file format it will work with third party applications, more about this in the 500 section
  • The screen is the same size as the 500, if you plan to upgrade from 305 to 500 no difference there.
  • There has been reports regarding the battery contacts breaking in the 305 causing the unit to switch off during operation. This can be repaired and you find instructions on the web on how to do this.
  • Slow satellite acquisition, the 305 takes a lot longer to acquire a satellite signal. If you don’t have the cadence/speed sensor it means you will be waiting for up to 2 minutes before your speedo starts working

DSC_0119

Garmin Edge 705

  • The satellite acquisition time is much better on the 705.
  • The screen size on the 705 is larger, as you would expect because of navigation and need to read the map while you ride.
  • Colour screen – but if you don’t use the maps this will mean little to you. Having coloured borders on your speedo means so little.
  • The size, you can see from the images, its big. I remember this was the biggest disappointment when I first got the 705.
  • The base maps (for Australia anyway) are next to useless. If you are planning to use this for touring you are going to have to pony up another $200+ for the detailed maps.

DSC_0118

Garmin Edge 500

  • Designed with racing in mind, this has all the features a racer needs without the on-board maps.
  • Initial version did not include work outs but if you upgrade to the latest firmware the work out functionality is included.
  • There have been a number of posts on the Garmin forums reporting various problems with the 500 unit such as corrupt data and the unit locking up. For what it is worth, mine has been working fine and I’m very happy with it. It is also worth noting that the 705 has a record of having problems with corrupted data files.
  • The data recording seems to be a lot more accurate than the older 705. If you have a look at my Canberra Climbs post there is an example of the how much the data recording has improved, (scroll to the bottom of the post for details).
  • Cool new features such as vertical speed and temperature. But it doesn’t calculate wind chill factor which would be really cool. The only problem is that no software records vertical speed so you can only make use of it while you are riding and the only software I have found that records the temperature is the Garmin Connect service.
  • The screen has an auto scroll feature, initially I thought this was cool but it can be annoying when you want to know your speed and it is on the wrong screen. Also if you press the stop button, the auto scroll also stops which means you might end on the wrong screen, but you can still advance it by pressing “enter”.
  • The size is the big winner for me with the 500. After moving from the 705, having the smaller screen took a bit of getting use to but you quickly adjust so no real problem there.
  • The button placement takes a little to be desired. The buttons are fine if you are wearing standard cycling mitts and you easily feel for the buttons on the side. In winter when you have thicker gloves on this becomes a bit of an issue. It’s harder to feel for the buttons and because of the “twist off” bracket design if you press the “enter” or “stop” buttons too hard you start to disengage the device from the bracket.
  • I’ll save the worse till last, the new file format. The 500 no longer uses the TCX file format to store the data. This means you are pretty much limited to using Garmin’s own software and services to transfer your data. You can still export your data from Garmin’s applications to the TCX format and then import them into your favourite application but that adds another step, which is a bit of a hassle. The only other application I have found that will work with the Garmin 500 file format is the Training Peaks WKO+ application but this does come at a cost of US$129.

The iPhone

I’ve thrown this in as a comparison, most phones like the iPhone have some form of GPS capability these days. With the iPhone in particular there are number of GPS applications which will track your ride for around $0 to $10. Bike mounts for iPhone are also readily available such as this one.

I wouldn’t consider this an option for the racing rider, its too big and the GPS accuracy and responsiveness is nothing like the Garmin units. But if you are into touring its another matter.

  • Given in Australia a 705 is going to cost around $500 plus $200 for the maps you’re well on the way to buying a GPS enabled phone outright.
  • The iPhone comes with Google maps included or you can buy another app for around $10.
  • The screen is bigger on the Iphone which map reading on the go much easier.
  • Obviously you can play your tunes as well on the Iphone, another bonus for those long lonely rides.
  • The Iphone is not waterproof, so no touring when it is raining.
  • I have issues with how proprietary the standards on the Iphone are but this is no different to having to buy the maps from Garmin so I guess they are even on that one.

So everything considered, I would highly recommend a Garmin 500 and if you need mapping as a feature seriously consider the phone option.
