Last Sunday was the day of the 4-Miles of Groningen. Arno van der Heyden (comedian) and Wilfred van Holst (race runner) took a measurement during the 4-Miles to see what kind of effect the effort had on their heartbeat. This measurement was made possible by Ingeborg Trul and the equipment by ProCare.

Besides the effort of Arno, Wilfred and many others, Lode Holding took part in the 4-Mijl
