Since 2010, the MOPO Relay Race has occupied a fixed place in the calendar of the race-mad GRASSL employees. Yesterday evening it was that time again. After months of training, four GRASSL teams set off on the 5 × 5 km stretch through the Hamburg Stadtpark. Cheered on by a great crowd of fans, the teams performed admirably to finish in 70^th, 436^th, 495^th and 647^th places.
