It worked pretty well, and I think will make the clients happy. Out of town through the Cascine, then back in on a loop in the beautiful park. On today's ride I took a bridge over to Scandicci, but I think for clients it would be better to do the whole loop in the Cascine then over Ponte Carraia to Porta Romana. Up the winding route to the turn off toward Galluzzo, the up to Poggio Imperiale. Down to Galluzzo, then over to Cinque Vie to Ponte a Ema, then up Via Carota (optional) and back to Bagno a Ripoli. Out toward Candeli from Bagno a Ripoli, then back to town on a beautiful little flat road by the Arno. Home past the stazione Campo de Marte. I think it will work. Here is the garmin link:

The view toward Fiesole from Via Carota.
Via Carota. Not sure if it will be on the "flat route" but will
definitely include it as an option. Adding this increases the
climbing by around 80 vertical meters.
