MPH for indoor cycling

It bugs me when I see folks showing 20+ mph on Strava

& it is from indoor cycling and I know that they are big & slow

& could never come close to that on the road.

I do a spin class & add it to my miles, but enter it manually so that it is neutral vs my average speed on the road.

Thoughts?

Check out Track records

Its UCI indoor velodrome season now.

Motor pacing until last couple laps , really boosts the finish line speed..

Homebound ?
speed sensor with optimistic input ?


Or its not that bad outside... you need to leave the tech home, and go ride your bike..

My thoughts are that you're overthinking it. For those who can't get outside due to weather, spinning is a great alternative, but no one is impressed by their numbers.

I've been trying to figure out how to equate a 50-min spin class to an outdoor ride over average rolling terrain. I'm fairly slow (15 mph), but I'd say 20 miles outside is roughly equivalent to 20 miles on the spin bike, although it takes longer outside.

Get used to it. There are lots of ways to cheat and new ways are being invented every day. Not so long ago, some fellow was complaining about people beating him up a hill using e-assist. I'm not much of a techie myself, but I found my average speed and distance are greatly improved when I forget to turn off my Garmin before driving home.

In the end, the only contest that counts is the one you hold with yourself. You get to set the rules and nobody else can cheat them.

If you really care about other folks being less than honest, you really have to stay off the internet. People lie and cheat. A lot. It's inherent to the species apparently. Nothing you can do but ignore them.

If you're concerned about not being able to do 20 mph on a trainer, reduce the tension to almost nothing on the real wheel and enjoy. Then someone else will wonder how you got 20 mph an hour on a trainer.

Not sure why anyone would think miles or mph on a trainer are in any way similar to miles ridden outside.

also not sure why anyone would see those numbers and think they are legitimate.

1000 miles ridden in the winter on a fluid trainer does not equal 1000 miles on the road. Same for mph.

Oh well.

Miles are miles

You will get a way harder workout indoors . you can do targeted training and get stronger , compared to riding in bad weather and pacing yourself .

cold weather Road rides with competitions lined up are as much for show as high speed numbers indoors .

If you think road rides are harder try to hold 25 plus mph for an hour indoors , you gonna need a mop .

Also on the road you can get free speed and wind boosts . as well as draft cars and other riders .

This. I log plenty of hours on the trainer in the winter. Watts, calories, time in the saddle - this all "counts." MPH or total miles is meaningless. I can change gears, which will change the mph readout, but be doing exactly the same workout, because resistance is set by power output. When my friends ask me how many miles I logged indoors for the winter, I say "0." Then I kick their butts on the road, because they are expecting that I've lost all my fitness :-)

Why would anyone care what someone else is posting on Strava?

Or on BF for that matter....


I belong to a couple of clubs, & scan the leaderboards to see who is riding well.

Don't think there is any intent to deceive, and you can certainly get a good workout on a trainer, etc.,

but some of the speeds would have folks in cat.1 & beyond when they are clearly not. I would be embarrassed.

A number of Strava users may be unaware that there is a difference between indoor vs. outdoor cycling. Ergo, awesome speeds posted could be unintentional.

A few years ago, I was doing indoor Computrainer sessions with a group of friends. One workout we would often do was a simulated climb up the Col de Tourmelet. The trainers could simulate increased resistance for the climb, but that resistance would not increase if we rode faster. Consequently, our "speeds" up the Col were close to 40 kph, peaking much higher as we approached the top of the climb. We weren't cheating, it was simply easier to ride faster in a higher gear. Indoor training miles are not really the same as outdoor miles. The smart trainer I use now is much more realistic than those Computrainers were, but it still does not provide the same experience that outdoor riding does

Simulated rises are hit or miss but for pure training no road can provide the resistance a trainer can unless you can spider bike up a building .

I think this was a problem with your CompuTrainer settings. In "courses" mode as you described, it should be harder to turn a big gear fast as compared to a smaller gear. Thus, when you gear down to find your comfortable cadence (or to simply be able to turn the crank), the speed readings should also drop. To make this work properly, you have to enter your weight accurately.
Where the CT courses become unrealistic is on the downhills, because there is no coasting. If you stop pedaling on a "downhill" on the CT, the system will record 0mph.

This was not one individual Computrainer. This was a class involving multiple stations. I was not the person responsible for programming the class I am simply recounting my experience. I thought that I made that clear

Yes. I understand that it was a class. I am very familiar with the MultiRider system. I am just saying that forum users should not stay away from the computrainer system based on your experience, as your experience seems likely due to a problem with the settings and is therefore not reflective of how the computrainer courses actually work.

I solve this by not comparing myself to others based on internet postings, rather only compare myself to others in real life. I think there is a name for these events, in which people gather under a set guideline for competition, under the watchful eye of an official body who determines whether said rules are adhered to, to compete head to head against one another in the same environment, and at the end of which a general classification is provided of how competitors finished in relation to one another (and generally all enjoy post event adult beverages), but I cannot remember what they are called right now...

I don't Strava or Zwift or whatever and don't keep track of my miles. I compare myself to other cyclists by height.

The resistance on my fluid trainer is far less than in real life. My avg flat road speed is around 18mph. On the trainer, easily 23+. So to achieve a good workout indoors, I have to maintain that speed for an hour, and I do rack up 20 miles quickly. Not exactly cheating, just the physical limitations of my equipment. Then again, my speed in a drafting pack isn't much less than my trainer. Keeping cool with no wind resistance isn't fun either.
I do admit, I wish my trainer had more resistance. I do feel guilty posting numbers I cannot achieve on real roads

You need to maintain at least 19 mph otherwise you will fall off the turns at the Velodrome
