Definitely. I had a training camp in Mallorca that finished literally the same day that Spain went into total lockdown, then I've been doing TrainerRoad 3x per week with an outside ride 1x per week. Usually I walk 3 miles each way to work and back, but working from home means my legs are totally fresh for cycling. I'm smashing PRs on Strava every time I go outside right now. Looking forward to another FTP test in 3 weeks time! Also lost 1.5kg!
