The Mincio River meets the south end of Lake Garda at Peschiera del Garda. Runners can go from Port Brescia south along the gravel Ciclovia Mantova-Peschiera multi-use path for up to 42 km to Mantua. Make it a one-way marathon! The first 14 km is gentle rolling hills, then it’s a gradual downhill after that. The path is well way-marked.
