I have been using an indoor smart trainer to complete all of my Fascat training workouts so far. I have recently acquired a new bike with power meter so thought that it might also be possible to perform some of my workouts outside now that the weather is getting warmer. However on my first couple of attempts, I seem to fail miserably to hold the required power when there is any incline or decline (and I live in a pretty flat area). My power varies dramatically, especially when compared to indoors.
Is it just a matter of skill to hold those watts outside or should I just stick to training indoors?
Any tips for me?
