Want to get the ST perspective on a question I often ask myself, yet have never really convinced myself of an answer I am willing to believe in. Outside of bike handling and shifting skills, from a purely training-response standpoint (e.g., not taking into account mental health, enjoyment, etc) is there any benefit to doing a longer-steady state ride outdoors versus on the trainer? I understand all the benefits of doing hard intervals on the trainer in terms of dialing in specificity, but what about long stuff. To illustrate and give a bit more context, I am often faced with this dilemma:
Let’s say that the prescribed workout is a 3 hour aerobic ride, say keeping the power anywhere between 200-230 watts, looking to average somewhere in the middle, but nothing too specific. I can fight traffic getting out of the city, and then navigate my way through some small towns with tons of lights, and then get out to some good road where I can do the ride. Kind of a pain in the ass, but at the end of the day, if I discount those few miles fighting through crowded areas, I come back having accomplished the time and power goal. Or, I can hook up to the trainer, put on some football, and just use gearing to mix up the wattage and cadence (more as a way to fight off boredom than anything else) and end up with the same numbers.
Again, I fully realize the handling benefits of riding outside, so I don’t want to start a debate about that. I suspect the answer is no difference, and maybe that the trainer ride is even better, but I am curious to hear thoughts and evidence. Yes, tomorrow is NFL Sunday, so I am asking myself this question right now and realized that I don’t really know why I make the decisions that I do. If there is a group to ride with outside or I’m hell-bent on feeling the wind at my back I go outside, but sometimes I just don’t care about that, and simply want a training effect, yet I still find myself leaning toward outdoors more than indoors.
Thanks.
