Very simple: more frequent but shorter rides. Typically this time of the year, I would do two or three weekday rides (approx. 90 minutes in length), a long ride on Saturday (200km or more), and a short recovery ride on Sunday (one hour, unless I'm doing a 600km audax). Now, I get out once per day for roughly an hour. Saturday and Sunday are reserved for longer rides (3-4 hours). Partly to keep sane (I'm stuck in the house 24 hrs per day by myself otherwise), partly to keep fit (I'm still planning to run a BRM 400 this summer, which needs to be route checked at some point).
