I just turned 80, and have been recording my cycling activities on Strava since 2019. I like to compare my rides with other senior cyclists, and segments allow me to do that. But, at age 80, I'm still competing segment-wise with 75 year-old cyclists. My suggestion is to replace the 75+ age group with 75-79, 80-84 and 85-90 age groups. This will not only make segment standings fairer for those over 79, but will also encourage older competitive cyclists to improve their conditioning.
