Been knocked out of riding for the better part of a month with this damn vertigo issue. Yesterday I got back on the bike and knocked out a 22 mile ride with no problems. Today I went to repeat the ride and ran out of gas after 5 miles or so. I still completed 14 miles, but it wasn't easy. I was doing 100+ miles per week at 20-25 miles per day almost every day at my peak last year and I kept up 100 mile/week on the trainer over the winter. But a month with only 4 rides really set me back. I've still been walking 3 miles every day even with the vertigo, but just being off the bike for most of a month has had a huge impact on my stamina. I can't imagine how tough it would be to come back if I were to catch COVID-19 or have some other issue where I was completely laid up for weeks.
As I'm always telling Wifey, it sux getting old, but at least it beats the alternative.
