    Zwift Cellular Data Usage Stats

    Zwift Cellular Data Usage Stats

    Australian Zwifter Stephen Jackson uses 4G data for his home Internet connection and is therefore quite wary of using too much data. He has been tracking Zwift’s data usage for the past few months and recently shared the numbers with me.

    Methodology

    Stephen used utilities to get the exact time length of his Zwift sessions and track the data usage of zwiftapp.exe (Zwift’s core computer software). The zwiftlauncher startup software doesn’t use much at all, so it was excluded from the results.

    Results

    Over 64 hours across 45 rides, the average data usage was 1.14 megabytes (MB) per minute. Watopia was the lowest at 1.10, London close at 1.14, and Richmond the high water mark of 1.37. Solo or group or racing didn’t affect data numbers, nor did the overall number of riders on Zwift. 

    If you extrapolate this data to four one-hour rides per week, you’re looking at ~1150MB of Zwift data usage per month, not including any app updates.

    UPDATE: received this from Stephen on 11/16/16: 
    Eric, the Zwiftapp.exe has increased its data usage in the past 10 days. Prior to 4 Nov it was 1.14MB per minute, and since then it has jumped to 2.30MB per minute. Only difference I can see is the numbers of riders has been climbing over 1,000 regularly.

    UPDATE: received this from Stephen on 2/8/17: 
    Updated stats, since the northern hemisphere has kicked in and popularity has climbed, the usage has held steady across all the courses at about 2MB per minute. I am seeing typically 2 to 3,000 riders and it doesn’t seem to vary too much now.

    Stephen has two tips for the Zwifters looking to conserve data:

    Tips for the data poor

    Stephen has two tips for the Zwifters looking to conserve data:

    • Zwift app updates can eat a lot of data quickly, so be careful – don’t have auto update selected.
    • To really save data, ride alone. Start your ride, disconnect from the Internet, ride for as long as you want, then reconnect to “end ride” and upload your ride file. Your usage will be about 10MB in total. It’s lonely, but a data cheap way to ride!

    Thanks for the numbers and tips, Stephen!

    Zwiftcast Episode 12

    Episode 12 of the Zwiftcast has been released, and includes an interview with Zwift Insider editor Eric Schlange! Here’s the full episode description:

    Simon, Shane and Nathan are back to discuss the increasingly lively – and populous – Zwift platform.

    We start this episode with a big discussion on the major success, and minor failings, of the Tacx World Champs series of races. Zwift VP of Marketing Steve Beckett answers questions on why around 10% of users had problems during the race – with Shane, Nathan and Simon, along with KISS race organisers, seeking some perspective on the event.

    With Zwift becoming ever busier, is it time for the opposition to walk in fear of the Zwift indoor riding bulldozer, or are they raising their game to compete? We discuss.

    A French academic working at a German University reveals the results of his research into how avatars in “exer-games”, like Zwift, may actually influence the performance of the user.

    Zwift community stalwart Eric Schlange makes a long-overdue appearance on the podcast to discuss his painstaking tests to find out which bikes are fastest on Zwift; discuss his IRL racing career and chew the fat a bit about expensive trainers.

    Zwifter Paul Stokes has been co-opted onto the Zwiftcast to review the new Elite Rampa trainer. What does an “ordinary Zwifter”, someone who doesn’t ride a whole lot of trainers, make of the rival to the Vortex and the SNAP?

    And we talk to Tam Burns, the man who’s coming back for a second bite at the cherry. After organising a massively popular mass participation race last year, when the lack of an event module made that an arduous task, Tam is again devoting time and energy to staging a big race. Why does he do it?

    Plus lots more Zwift-related chat on a whole lot of subjects that all Zwifters should find of interest.

    Which computer runs Zwift best? Ask Zwiftalizer Benchmarks.

    Mike Hanney has launched a new feature on his excellent Zwiftalizer log analyzer site which consolidates the results of the many log files Zwifters have shared and reports on the performance of various hardware setups in an easy-to-read format.

    See the results at zwiftalizer.com/benchmarks >

    According to Mike’s FAQ, he put these benchmarks together “To know when enough is enough… to make informed purchasing decisions…” Zwifters often ask questions like, “If I buy this computer, will it run Zwift at a high resolution and framerate?” These benchmarks tell us that answer.

    Results are grouped by resolution (from 2160 Ultra down to 576 basic), then within each of those groups displayed by their unique OS/CPU/GPU “signature.” This allows Zwiftalizer to consolidate results from multiple users who are running the same hardware into one benchmark.

    As of today there are a total of 182 different system signatures benchmarked. Got a spare minute? Help expand these benchmarks by uploading your Zwift log to Zwiftalizer.

    Nice work, Mike!

    DC Rainmaker releases annual winter trainer recommendations

    DC Rainmaker releases annual winter trainer recommendations

    I’m a big fan of Ray Maker of DC Rainmaker fame. His product reviews are consistently thorough and non-biased. On top of that, I’ve put them to good use numerous times when researching smart trainers: his reviews are arguably the number one resource for smart trainer shoppers.

    Ray has just posted his big annual trainer recommendation post–you can read it here >

    Ray divides trainers into three groups:

    • Budget – Sub-$400
    • Mid-Range $400-$1,000
    • High-End $1,000+

    If you’re looking to purchase a smart trainer this season, I highly recommend heading over to DCRainmaker.com to do your research.

    Save the date: Ride On for World Bicycle Relief Zwiftathon December 3

    Last year was Zwift’s first “Ride On for World Bicycle Relief” day, in which Zwifters were challenged to ride 100,000 miles in order for Trek to donate $40,000 for World Bicycle Relief. It was a wonderful day, with many thousands of riders turning out to ride anything from short stints to mammoth, multiple-hundred mile efforts on WBR’s signature Buffalo Bike. And the 100,000 mile goal was hit quite easily!

    I personally completed my first 100km Zwift session that day, all the while chatting with a group of friends on Teamspeak as we rode together.

    Zwift HQ has announced this year’s event, taking place Saturday, December 3.

    wbr-announcement

    According to the World Bicycle Relief event page, prizes will be awarded (how to qualify for the prizes isn’t currently clear), including a Hammer Direct Drive Trainer from CycleOps and a custom Trek Project One Madone! Also, professional cyclists Jens Voigt, Laurens ten Dam, Mirinda Carfrae, Jordan Rapp (and many more) will be riding on Zwift during the event.

    More details are still to come from Zwift HQ, but everyone is encouraged to save the date and participate in some way.

    Zwift Halloween Hammerfest announced

    hammerfest-logoTrapper Markelz, organizer of various Zwift Hammerfest events, has returned from a summer of outdoor riding and business commitments to host his first Hammerfest of the season: the Halloween Hammerfest!

    To participate, just register at hammerfest.bike.

    Here’s the event description:

    This five day, three stage Hammerfest will put you into a caloric deficit that you can fill with Halloween candy! It all starts off with a gut wrenching KOM of Box Hill on the London course. We then switch to Watopia for a single island lap. Then it gets crazy with something we’ve never tried before: A whole mess of sprints.  Complete the segments identified for each stage in the time allotted and upload a result to Strava. For more details about how this works, check out the FAQ.

    Stage 1 – Box Hill KOM – Oct 24th and 25th
    The Hammerfest kicks off with a 1.9 mile (3.06 km) hike up Box Hill on the London course. We are using the Zwift Insider Verified segment. Get ready to throw down a PR. We have faith in your suffering.

    Stage 2 – Watopia Single Lap – Oct 26th and 27th
    It all started with a simple hilly loop around the island. We are going back to basics on this one with a drop-dead-simple old-school original island circumnavigation.

    Stage 3 – Watopia Sprint Fest – Oct 28th – 29th
    Are you ready for this? It is going to be crazy (awesome). Go to the sprint segment on Watopia (the one that starts under the tunnel) and we will total up your best six (6) attempts into your total time. Sprint, U-turn, Sprint, U-turn, repeat!

    Wondering how the Hammerfest events work? Read this description.

    Zwiftcast Episode 11

    Episode 11 of Zwiftcast has been released. Here’s the full episode description:


    Shane, Nathan and Simon are back together for the first time in a couple of episodes to discuss all matters Zwift. The boys kick off with a discussion on how “refuseniks” now seem to be flocking into Zwift; catch up on the latest Zwift on  iOS chatter and summarise how things have been going in Australia as the end of the indoor season nears.

    There’s a short feature comparing the noise emitted by the new Wahoo KICKR compared to the older version and a discussion on whether noise could be the new battleground in the fiercely-competitive Smart Trainer market.

    After hearing from Zwifter Peter Maloney about how he’d like to find other Zwifters riding on with multiple sclerosis by changing his name to indicate he has the condition, Simon, Shane and Nathan go on to discuss the tendency for people to change their real names in the game, wondering whether anonymity is a good thing or not.

    One of the KISS race series organisers Glen Knight is on the Zwiftcast to discuss the upcoming Tacx World Championships and Simon, Shane and Nathan discuss which nation may be favourite to take the title.

    Experienced Zwifter Antony Henson tests out two of the top of the range trainers, to help Zwifters who may be in the market for a Smart Trainer this season to make a decision. Is the Tacx Neo or the Wahoo KICKR the best buy?

    And veteran indoor rider Colin Peerman gives his verdict on the value of the best Smart Trainers – compared to the many other trainers he’s owned.

    Simon, Shane and Nathan round off this edition with a lively discussion on how race starts can best be regulated in Zwift.
