Elemental Technologies and Ericsson have laid down the gauntlet in the run-up to IBC. The 4k 4Chartity Corporate Challenge is part of the 4k 4Charity Fun Run, taking place at 7.30am on 12th September, in Amsterdam. Companies can use the opportunity to register and issue company-to-company challenges; a leaderboard at http://tinyurl.com/pqhes8r will track the top five companies by number of registrations and donations. Winners will be recognised on race day, and at an event afterwards. All proceeds will go to Care, a charity dedicated to fighting global poverty.
