The course
Pick a distance: the map draws its course, with the elevation profile below. Under the map, the same course in words, place by place.
The courses on the map were redrawn by Competi.ro on OpenStreetMap from the routes the organiser published on Strava; they are not the official files. Map data © OpenStreetMap contributors (ODbL).
On the 21K, lap two repeats the circuit and adds an out-and-back on Bulevardul Mihail Kogălniceanu, turning near Piața Kogălniceanu (around km 16). Aid stations: km 5.5, 11 and 16.5, plus the finish.
The whole course sits between 73 and 90 m: highest on Kiseleff by the Arcul de Triumf, lowest on Bulevardul Regina Elisabeta by Cișmigiu.
