Using Garmin 910XT With Ubuntu Linux (Part 1)

Garmin Forerunner 910XT

My primary (recently only) OS is Ubuntu Linux, and I’ve been struggling to set up device sync with my Garmin 910XT on Linux. Figured it out today, and thought I’d post it here for reference. (This post refers to getting the data off the device and on to the system. In 2nd post of the series, will add instructions to then upload it using Garmin Connect).

Here’s what I did:

  1. Downloaded the drivers branch of ‘Garmin Forerunner 610 Extractor’ from Github as a zip file, and extracted it to a folder on my drive. For me, this folder was at ‘~/Dropbox/Misc/GarminOnLinux/Garmin-Forerunner-610-Extractor-drivers/
  2. As suggested in the notes on Github (and included README), ran the following command to make it easy to run the sync without using sudo. Didn’t work for me, but your results may vary:

    cd Dropbox/Misc/GarminOnLinux/Garmin-Forerunner-610-Extractor-drivers/
    sudo cp resources/ant-usbstick2.rules /etc/udev/rules.d

  3. Installed pyusb. I used pip to install:

    pip install pyusb

  4. Connected the ANT+ USB stick at /dev/ttyUSB0. Inserted the USB stick, and ran the command below:

    lsusb | grep Dynastream

    This gives an output of the form like: ‘Bus 003 Device 002: ID 0fcf:1009 Dynastream Innovations, Inc.‘.
    Used the information from this output in the next command:

    sudo modprobe usbserial vendor=0x0fcf product=0x1009

  5. Everything is now setup, so switched on the Forerunner watch, with pairing switched on. After a short wait to allow for pairing, ran the Forerunner extractor1:

    sudo python garmin.py

That’s it. The final command initiated a complete download from my Forerunner 910XT, files being stored in ‘~/.config/garmin-extractor/XXXXXXX/', XXXXXXX being a number that varies from device to device.

First encounter with Box Hill

Surrey Downs & Box Hill ride

The original plan was to ride to Brighton but having started really late, it became clear by the 1/3rd distance mark that I wasn’t going to make it in time for a return train. So, after getting over the Surrey Downs, I changed route and headed over to the famous Box Hill.

Frankly, it was a disappointment at first. I kept waiting for a killer climb but nothing came and suddenly I found myself in middle of the Box Hill village. This famous climb into Box Hill is featuring prominently in the road race at next year’s Olympics yet even the couple of Cat 5 climbs (acc to MapMyRide) in Surrey Downs had been much harder. The disappointment (actually, relief) was short-lived.

A quick review of the area on Google Maps in terrain view revealed a sharply rising road on other side of the village called, appropriately, Zig Zag road. At that point, I had two options – to head back the way I had come and just mark Box Hill as conquered or to head down the Zig Zag road and see for myself how much of a challenge it’d be.

Well, when I looked up after the first switchback on the way down to see how high the car I had just passed was, it became clear I may have bitten more than my legs & wheels could chew. Thankfully, I still had an exit clause. I could take an alternate route by passing Box Hill and climbing barely half of what ZZ road required in over 4 times the distance.

Took a short break, had a sizzling hot hotdog, a pepsi and some rest. Also used the time to research a bit and discovered that it was this Zig Zag road clilmb that was to feature on the Olympic road race route, not the easy tweasy route I had taken up earlier.

That bit of info was reason enough, so headed back up the Zig Zag rd.

Thankfully, saw a couple of other riders on MTBs just about 100m ahead of me so put in a bit of extra effort and quickly caught up with them. After that it was just a matter of using whatever of my will- & leg-power I could muster to stick with them. Made the climb without stopping even once and at least half the credit goes to those two fellas. Having them around prevented me from giving up midway or even stopping to take a break. It was the first time I realised how having a training partner, or few, could help one stretch self farther and improve faster.

After cresting the hill and passing through the village, it was a clean, mostly level or slightly downhill, 12 km stretch before I hit civilisation and red lights again. So, gave it a go and averaged, despite three red lights a little over 30kmph in that section. Once I entered Sutton though, it was just another urban ride with the magic of Surrey Downs and Box Hill well behind me. It became so boring that after a short break to buy some water, I even forgot to start the garmin (add 2.6km to the distance in the pic above for actual ride distance). Took a slightly roundabout way home so I could complete 100kms on the garmin and tick off this week’s century ride.

Done :)

P.S.: Just saw that I have totalled 859kms so far in June. Wondering if I should go for a 41-ish km ride tomorrow to take that total above 900 mark :)
P.P.S.: Total for the year, despite the dismal first 4 months, now reads 1200 miles. Still 520 odd miles short of Martin. I had planned to equal his mileage this year. Seems now like a tough ask.

First encounter with Box Hill

First 100 miler

Failed to reach the target destination but still completed my first imperial century yesterday.

Had planned to ride to King’s Lynn on the North Sea coast in Norfolk. Unfortunately, a late departure meant I wasn’t sure I’d make it in time for the last train to London. So, stopped at a small town (or large village?) about 10 miles earlier. The distance already read 156km so rode around the town to take it over 161km mark :)

SJW To Downham

I’ve got a problem though. Every time I come back from one of these longish rides, the body just refuses to cool down. Like yesterday, though I took a long shower right after getting back, the body stayed burning hot till late into the night. It almost felt like somewhere inside the body was still burning calories at the same rate as while riding at the peak. 2nd consecutive ride this happened and I have no idea how to stop that. Any help is really, really, REALLY appreciated!

P.S.: The sun killed me! The temperature was only 25-27 C but was downing humongous amounts of water and still feeling dehydrated-ish all the time.

P.P.S: Haven’t test ridden the Synapse yet. If I can stay awake, then might test ride it today.

First 100 miler

2nd metric century within a week Rode to…

2nd metric century within a week. Rode to Cambridge today, about 102.5 kms, and took the train back. Wonderful ride. No hills (unlike the Chilterns enroute to Oxford) and luckily, didn’t get any rain on me, though the roads were pretty wet in places.

SJW To Cambridge - 2nd metric century

Also, trying the Cannondale Synapse tomorrow. If I like how it rides, might buy it as soon as we’ve moved to the new place.

Status

A century… finally!

1st Metric Century

Completed my 1st metric century today. Am damn happy to have finally gotten this behind me and amused by the manner in which it finally got done :)

Thing is I’d attempted this multiple times last October & November. Unfortunately, the October attempts were marred by the rotten, bent rear wheel and the November ones by sudden rains and (once) snowfall. The result is that I have a dozen rides between 80 & 95kms in those two months.

Well today’s ride was planned to be a 75km straight return to / from Windsor. Despite the strong head/cross wind on the way back, decided to take a detour towards Wandsworth to check out the bikes at the (bigger) Evans Cycles outlet there. As a result of that diversion it was already 83kms by the time I made it to Hyde Park and I wasn’t really feeling too tired. So, decided to take another small detour and do a lap of Regent’s Park and return via Camden Town. Just about made it across the century mark before making it home.

The best thing about the ride – the legs were feeling good even after I’d gotten home so with another small break added, I think I can make it past an imperial century as well. Of course, only if I can find a long enough route without too many hills and am lucky with the rain and wheel!

Shall feel good with this for now :)

A century… finally!

Ride 8, 2011 – Uxbridge

Ride 8, 2011 - Uxbridge

My closest relative in this country, dad’s elder brother, lives in Uxbridge. Being the eldest son, he had gone to India for grandpa’s last rites and only came back last week. So, last Friday I went over to see him. There was also the small matter of collecting the barfi (Indian sweet) that Ma had sent for me through him :D

The ride, overall, was pretty easy – hardly any inclines, only a light headwind and temperatures not too much below double digits.

But (yes, there’s always a but), that didn’t meant there were not hiccups. For one, on the ride to Uxbridge, I decided to avoid the main roads as long as possible. That meant I had to take the inner roads with lotsa turns which meant just one thing – stopping every 500m to check the map on phone. That meant no momentum and really no ensoiment*. Was further disappointed when I finally did join the main road (A4020/Uxbridge Road) and saw that the road had dedicated cycle lanes and paths on both sides while I’d been struggling with directions and traffic on the smaller roads avoiding it.

Had a good time with Tayaji (north Indian term for dad’s elder brother) including a long chat that wouldn’t have usually happened if we had our better halves around. He even made coffee for us :)

The trip back should’ve been much easier with the earlier discovered bike lanes and the wind on my back. Unfortunately, barely 3 kms into the ride back, I felt the back tyre touching the breaks. A quick check confirmed the fears – it was out of shape again. It also reminded me that I’d forgotten to restart the GPS on the way back. I loosened the brakes enough to stop the touching but the ride thereafter was cautious, and unhappy. I haven’t ridden 500kms since I got the bike back from Evans after wheel truing last time and it’s spoilt again.

Nevertheless, the ride was easy – cycle lane to Shepherd Bush and then a quick straight route home through Notting Hill and Maida Vale. A nice and simple 50km ride to-from Uxbridge.
