I have acquired a Wahoo Kickr and am looking for advice on the most appropriate apps to suit my needs. I am 82 and post hip replacement and cardiac arrest 3 years ago,so serious training is irrelevant,but am still interested in the numbers.I mostly ride alone on the road but am competent in bunches as long as I can keep up,last year I was doing 26 or 27 minute 10mile TTs but nothing this year.As I feel the cold more nowadays I wont go out when it is<5C,snow,or very windy so intend to use the turbo in the garage to maintain fitness.Research so far suggests the choice lies between Zwift and Rouvy. Sensible comments please!
