Strava tells me that my mileage agg for this year (trainer early, outdoors once weather turned) just passed 1,000 yesterday. Total time actually moving? 75 hours, giving an average of 13.4 mph.

On a trainer where there's no wind, or outdoors when climbing, what's the % between incremental miles per hour look like up to maybe 20?

Don't remind me of that too often please. You have memories of where you were in 1974? At 76 now I can barely remember what 25 even felt like...
