Personally not sure if I’d use it. Time is short and trainer is more time efficient so used for 90% of my non race riding. If I do ride outside then usually social so not interested in workout or easy enough to replicate anyway. E.g. do 15 min intervals as sweet spot or 3 min hard repeats etc. I had to miss Bashful the other day (due to a hangover I’m afraid to say!) so rode to work the next day and did one minute repeats hard/easy.
I feel lots will say yes please…but not sure really use it - not that hard to replicate workouts outdoors in terms of knowing what to do…it’s being able to actually do the intervals without stops/traffic/hills etc getting in the way…which brings me back to indoors being more efficient.
Just my devil’s advocate 2p worth!
