The innovative DSC1000 portable barrier and TB100 portable bollard systems from Delta Scientific were recently rented from Australian-based Knight Brothers to help protect the 85,000 entrants in the world's largest run on 11 August. Both a fun run and a competitive contest, the City2surf Run covers a 14 kilometer (8.7 mile) course that begins in Sydney's Central Business District (CBD) and culminates at scenic Bondi Beach.
