Olav Gruppen organiseert heel kleinschalig een loop over de Gerrit Krolbrug:<\/p>\n
Door schade na een aanvaring, zijn er twee routes over de Gerrit Krolbrug: linksom een wandelroute, en rechtsom een fietsroute. Die kun je ook achter elkaar plakken voor een rondje. En dat doen we dus 100 keer!<\/p>\n
Deze ultramarathon is niet verzorgd: er is geen sanitair en geen eten\/drinken. Met een beetje geluk kun je gebruik maken van openbare toiletten – bijvoorbeeld de Basic Fit op 100 meter van de route. Maar ik kan hier niets over beloven. <\/p>\n
