I created a web app to analyze your outdoor routes

ok, I think I understand, but rather than setting the minimum target power.

Currently, I think. knowing my FTP and deciding what IF I want to ride the route at, I will have to manually calculate my minimum target power and then insert that information?

You could input the FTP current (or where you would like it to be for riding the route) and then input the Intensity factor depending on the type of race, this would then calculate the minimum target power.

See the bottom of this article for varying IF’s depending on the type of riding you would be doing when looking at route analysis https://help.trainingpeaks.com/hc/en-us/articles/204071814-Intensity-Factor-IF

my solution to this right one is gradualy change min power until i reach my desired if. i could reverse it but calculations will be a little different as you try to create a simulation with the output in mind instead of input. i will think about it. also another think i was thinking is maybe the ability to set min power,speed etc for different distance ranges of the route. this could really help people simulate races rather than training rides but on the other hand it will increase the inputs and make the reverse simulation we are talking about more tedious

also i am just letting know that for people in europe and usa right now you can create routes in app without importing gpx. it might get a little slow on 500+km routes as algorith is not optimized but i am working on this

Sorry for multiple replies but I was at work. Don’t think minimum power as minimum power its more like target power average power. It will go up only if your speed falls in an ascent lower than minimum speed and will go down only if speed is bigger than max speed. In most cases min power = avg power. I could create the ability to add segments like the ones I did for drafting were you could choose different target power ,min and max speed for different parts of the route to simulate racing conditions better. The only reason I didn’t did that is that I feel the app gets more complicated than what people would actually need

Perhaps have a look at Best Bike Split Best Bike Split - Cycling Race Pacing and Power Plan Optimization, you can create a free account, I think for the first 2 weeks you have full function to see, after that it is limited in certain aspects.

The way coaches will look at route analysis will be based on a cyclists FTP and the IF to be applied depending on the type of riding. Various IF factors I highlighted earlier in a Trainingpeaks link,

Being able to input FTP, IF and forecast weather conditions, you can then route analyse a GPX to output overall time and will also target power, both Average Power and Normalised power.

Rather than incrementally adjusting target (minimum) power to get the desired IF.

FTP and IF are known inputs depending on the riding doing. Many who would like to analyse have no idea what their required target power should be, hence using FTP and IF to calculate target power and then have adjustment shown based on the GXP profile. It is not having an output in mind, but inputting known factors, i.e FTP and IF (for the type of cycling you are doing)

thanks. i will look into it more. this is really helpful as i am just a begineer in the cycling world and i see things more from the dev perspective rather than the cyclist’s

Cool, you can also think of it as similar to building a workout in ERG, with a workout the riders FTP is set/known, you set the % FTP for the workout (intensity factor), the only difference is that rather than a set distance block it is a GPX distance with elevation and weather inputs. The time it takes to do the workout will then be calculated.

i.e, creating a workout Zone 2 ride @ 60% FTP for 10km, The FTP is known, you input the %FTP (intensity factor), which will calculate the average power and you are riding for 10km workout block, with the only difference will be it is a 10km GPX file in this case, being the route you want to analyse.

Then based on your known FTP, the known Intensity Factor, that you want to ride i,e, Zone 2 and the known distance (GPX), you will then be able to analyse the route and calculate how long it will take you to ride that route.

Then there are scenarios where either the FTP or IF and changed, say you are road racing, or doing a time trial, then the average power and time to complete the course will then adjust in the calculations, based on these adjustments.

Hopefully the change in calculations/analysis is not too difficult to implement as you are using FTP and IF to calculate the average power, rather than inputting average power.
