Cycling Routes Siesta Key / Sarasota FL?

Can anyone recommend road bike routes departing in Sarasota (closer to the Siesta Key area) for 20-50 miles on relatively safe roads?

Thank you

there is the rail trail that runs from sarasota to venice. although i prefer going along all the keys as its more scenic. the rail trail has more shade

Strava’s route builder is great for this. But riding in that area definitely isn’t great
