Piazza (plaza) San Giovanni, with a route that passed famous city landmarks including the Ponte Vecchio, Piazzale Michelangelo and Piazza della Signoria.
We received a nice T-shirt at the finish. In a city where everything costs more, this race was a value. A nominal 8 Euros = $12 was charged. What a wonderful way to integrate into a community. As long as there's at least one runner to pass, I'll be pounding out the competition when I can.
