The thing I find jaw dropping is the cost of, and the number of people prepared to pay it, a full smart trainer set up. A friend recently purchased a Tacx, Zwift subscription, paid for a cassette to be fitted, purchased a bluetooth dongle, fan, rubber mat and various other bits. For what? The chance to pedal in the lounge in a fantasy, virtual world with "friends." I find it quite astonishing. The same money would buy a brand new Cannondale Synapse all set up as a winter bike.
Me? I sign up for the local gym at £27.99/month on a monthly basis. 44 spin classes included per week, 40 of them run by a coach who specialises in cyclist centred classes. The gym offers me a free month for every person who signs up on my recommendation - two so far - and I only plan to be a member for 4 months.
