Structured interval training has long been known to generate significant improvements to your cycling performance. Hurts Ergo offers a series of basic workouts to get going on your indoor trainer, once mastered there's access to the online ErgDB library containing over 600 unique workouts.

Hurts Ergo guides you through structured intervals using a target power value based on your own Functional Threshold Power (FTP). To best make use of the app you'll need access to a power meter, or a Wahoo Fitness KICKR trainer; both of which are optional.

My first experience is mixed. 2 of first 5 workouts were crashed with no possibility to recover data. One workout was lost as app suddenly frozen. I used to export structured workouts from Training Peaks and execute it using this app. Successful attempts take place if I initially clean Hurts ergo from device memory and load it once more. I miss the possibility of sound alerts before the critical power changes as I had in Sufferfest. No possibility to export data on strava and training peaks simultaneously. I used to export data to TP and then manually export to strava. All in all not a great initial experience(

No longer supported

I bought this app thinking I would be able to download and use the 600 workouts mentioned here and on the developers website. Unfortunately that database no longer exists (73 Summits) and if you click the button in the app to acces the DB it will hang the app. No problem, I will write my own and upload them. Well that functionality also does not work. I tried to upload erg files using the method on the developers website and found that I cannot write to the favorites folder. I have sent two emails to the developer for help and never received a response. So I am left with a useless app with 5 basic workouts. Total waste of time and money.

Easy to Set Up & Start Training

Was very easy to get set up without having to feed a bunch of data or complete user profile info that most apps want for their own use.

I use it with Kickr and export my Training Peaks workout and in a matter of seconds I'm able to start my ride. Best thing, I don't have to think about anything - no watching the wattage or the time off or on. Just follow what my coach has for me. Perfect.
