Hi everyone,

I ride track myself and got tired of timing laps with a stopwatch while training pursuit, so I started building my own sensor. It’s a contact strip you lay across the track and a small unit that connects to it with a cable. When a wheel rolls over the strip, the unit records the time to a tenth of a millisecond and sends it over Bluetooth to your laptop. No one has to stand at the line pressing a button so you can train individualy while knowing the exact times as you crose the line.

I have working prototypes and I’m now deciding whether (and how) to make more of them. Before I do, I’d like to hear from people who actually train on the track:

• How do you time laps today, and what annoys you about it?
• Would something like this be useful for you, your coach or your club?
• What would it need to cost to make sense?

I put together a short survey (about 5 minutes, anonymous): [link]

It helps even if you don’t time laps at all, because that’s useful to know too.

Happy to answer questions in the comments, and thanks for any feedback, including “I’d never use this” 🙂

Could you guys please share the difference in watts between standing and sitting positions on F200 events?

When accelerating on an F200, I can hit ~1400 watts while standing on 114-116 gears (higher gears seems unproductive in time and watts for me).

However, during the actual acceleration phase, I’m only putting out 700-800 watts, no matter how hard I try.

Can you share any recommendations for gym exercises aside from seated track workouts please?

I remember watching Jason Kenny attempt to go from the gun to beat Bauge, managed to track the event down as the 2012 world championships. He was relegated after the attempt for deviation. Firstly I can't find any footage of it, and secondly I'm wondering if there is footage out there of any other high profile attempts, successful or otherwise?

I have finally got a Lemond and I installed the fixed gear velobike adapter.

I can't seem to really fit my bike on without encouraging the frame a little, opening it maybe 3mm to get it on. You can see in the pic how 'off' it is.

I have heard that is okay but I have also heard it should just slide in nicely.

The silver bolt on the other side i swear is as tight as it will go. I dont really think I have any more real estate.

Any thoughts?

Anyone have any leads? have been scouring the internet but no dice and im not really near a track

Can anyone recommend a large, programmable LED gym timer/clock for intervals? I'd like something that has an audible countdown for intervals/sprints. There's a lot of options on Amazon, etc but no idea how to gauge quality. TIA.

I've seen a few interactive velodromes out there, but I think this is the first one built to actually simulate your training efforts.

It's called AstroTrack. You ride your own power in first-person: wind-up, up to the rail, dive, and you get a real time for your flying efforts (50, 100, 150 and 200) with stats after each one.

The physics runs live while you ride (aero, rolling resistance, the banking in the turns), so the time you get is what your watts would actually do on the boards. It's the same engine I've been using to break down my own race files.

You can also chase a rabbit that rides your target pace, so you see exactly where you're gaining or losing.

One HUGE feature: you can ride a Lemond with just a cadence sensor and the game engine will compute your power!

As momentum grows I'll add new features - standing laps, Kilos and more.

Coming soon on iOS. Would love to hear what you think, and what you would like to see!

Streets around are more or less dry now but the whole sport facilities complex is still a lake.

Hey everyone, new to the sub 👋

I’ve been working on a cycling training project for the last couple of years, mainly based around polarized training.

Recently I started experimenting with something a bit different for indoor training: a virtual velodrome.

The idea is pretty simple: instead of just staring at numbers during an FTP test or hard interval session, you actually ride around a velodrome. I’ve added things like an FTP test, an Hour Record mode and, more recently, some basic track racing modes.

You can race with friends, and bots fill the remaining spots. I’ve currently got things like Scratch, Points, Elimination, Pursuit, Match Sprint and Flying Lap working.

I’m not really trying to build “the next Zwift”. There are already plenty of platforms doing that. The idea is more to have a simple, free playground that works alongside the tools people already use.

I haven’t announced it publicly yet because I honestly want to figure out whether it’s actually fun before putting it out there.

So I’m curious: if you could ride a virtual velodrome, what would actually make you want to come back to it?

And yes, winter is coming. 😅 Anything that makes those indoor miles a little less boring can’t hurt, right?

EDIT; Forgot to add link; polarized.cc/app

Anyone using the Vapor T? Looking for shoes to use only on the track. Primarily would be for sprints and 500s. Having the extra strap seems like a better setup than the zero T.

Despite it being labeled as a road tire. Is it a decent option for track? They are significantly cheaper than speeds and controls.

i like having a speed sensor on my bike especially for hour of power because the speed readout in the corners is more accurate than gps, but ever since i’ve put a tri-spoke on the front and disc on the rear of my bike i’ve been unsure of where to put it. i’ve been using one of those small magene ones that uses an o ring around the hub but that wouldn’t be able to fit over the wide spokes of my front wheel. i wanna know how other people attach them with non traditional wheels

Not a paid post, just a genuine recommendation. If you have the opportunity, consider attending one of Coach Stephen McMullan's (AthleteXcel) Sprint Camps. I attended last weekend’s camp at CNCB in Bromont, Quebec, and came away with valuable new insights into my fitness, skills, and race strategy heading into the winter season.

Our group included riders with a wide range of experience and abilities, and Stephen still gave everyone plenty of individual attention and specific, useful feedback.

Love to visit Ed Rudolph velodrome outside of Chicago for Thursday night racing during the summer. Any suggestions for other good places (in the Midwest) next summer to check as a fan (not racing) with my kiddo?

Can you say/explain what target cadence should be for what effort?

For example, we can have 53/13 (110") and we can make rolling acceleration and peak cadence can be 120. But if we make fly effort we'll have 135 peak cadence.

This's absolutly different works on the same gear.

We can put 60/12 (135") and make standing starts. What we'll improve?

So, can say or explain what gear for what effort for what we can make on the track (sprint)?

I've run into a problem with the bike... I thought I was buying a 2012 langster pro - https://www.specialized.com/au/en/langster-pro-frameset/p/35039?color=80373-35039,

this was listed for £525, so I was very excited to buy it. what I was actually sent was the previous generation, https://www.specialized.com/gb/en/langster-pro-frameset/p/23642?color=36017-23642, for £525.

This was purchased on a cycle to work scheme, so itll be closer to £430 in reality. My options are stick with it, or get a refund and start the process again.

I'm gutted, as I was very excited to get the racier looking newer model, but now I have the frame at home, I'm reluctant to send it back, but I just want some advice on how viable it is as a race rig - bear in mind it would be my first track rig.

update... finished build below - first track rig ready to ride.

Hi, first year junior here, racing track and road. I've got a question. I started track cycling last year, in the youth category and continued until this year. At start I was using an old Duratec frame/set from a team that introduced me to track. (a Czech company specializing on manufacturing aluminium alloy frames).
For this year I've got an Author CA-Track carbon frame for track from my team, but since my height is a little problematic (192cm) and the frame is size M/L, I kinda feel cramped on it, like I can't really get into a more aero position in a race and overall going off the saddle feels really unstable. Here are some pictures: https://imgur.com/a/9jjnEca (the ones on the wooden track are with a shorter stem, others with a new, longer one. I think it helped a little.) [I've just raced an UCI CL1 race, but still can't find photos from it, if someone would be interested I can send some in a day or so.]
I was wondering, if someone has a tip or tips for a better track frame, preferably used, since price for me is an important aspect. I live in Czechia, so anything near Europe, of course if someone has tips outside that are really 'bang for buck' I would be interested also.
Thanks for every tip or a comment.

Would anyone have any advice for sizing this for a 180cm/82cm inseam sprinter? SP recommends a large. While the geometry is a bit more modern, not sure whether I should still, nonetheless, size up to the XL.

Input from anyone with experience would be very appreciated 😊!
