Ok if everything you own is a 2017 model


Want to use older MacbookPro so I can just leave it all set up on my trainer and not have to mess around with it every morning - nope, not supported!
OK - I'll download Google Chrome - too old, not supported! Same with Firefox!
OK - I'll use Apple TV - nope, not supported!
OK - I'll use my iPhone and Screen Mirror - nope, need to purchase a $70 dongle!
OK - I'll use W10 pc - total pain in the a**e because I use this for work so will need to reconnect every day. Ordered ANT+ - still connecting devices after unplugging and plugging in ANT+ 2765 times (even though my cadence and HR are showing on the screen), guess I need to now order a USB extension (I live in the sticks).
By the time I have everything hooked up the 7 day trial will be finished, I could have changed my trainer tyre 100 times and the seasons will have changed enabling me to go outside and cycle.
I am sure if you have a few thousand $ to spend on a fantastic trainer or if you are someone that runs to the Apple Store to purchase the latest iPhone on release then this app is great - but for me, it's useless!

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.
