Solomon Tesfamariam - Athlete from Eritrea was 10th in the Streetrun of Basel (10km). I like the paint like feeling of it.
It is a 28mm with 1/10sec and flash on second curtain, panning with the runners.
See the winners here and action there.
Light: AL + ETTL flash -1ev and manually chosen f 2.5, 1/10 sec ISO 400.
