Pain (and love) through suffering


I have been using the app on and off for years. I will say that the latest version is by far the best training app that I have seen out there. It integrates so much across just about every platform. It also works well with Garmin, Strava, training peaks and just about everything else out there. The developers and creative folks behind this app truly make it a fun and worthwhile experience… Even through the pain!!! Oh the pain.

Love the 4DP


I wasn’t sure about trying Sufferfest, but already after 2 days, I was sold :).
The 4DP test is brutal but awesome, nothing like any other FTP out there. The structured workouts are great. The guidance, comments and music are second to none.
I would like to see a way of selecting 2 workouts beforehand so I don’t have to stop.
I only have the Cycleops Fluid2 but I see how a smart trainer will put this at a hole different level.
Looking forward to another Sufferfest later this evening.

4DP is nice. But setting custom levels is a must


Sufferfest is trying too hard. 3 hour Tour stages. 4DP?
Why can’t I customize every is way too low and intervals too high. Much better to let us (the paying masses) over write the power so we can actually get through a workout. It’s not that my ftp is wrong (that would contribute) but a serious tool should let the user have full control.

I think I’ll go back to trainer road and my pre purchased vids and hammer away. Shoot I could get the timings and just ride the vids in another window.
