Over in the Czech Republic our POWERbreathe distributors for the Czech Republic & Slovakia (Truconnexion) had a booth at a cycling marathon event in Teplice with 450 racers on Saturday 11th August where they did demo’s with the K5 and also held a competition for the highest test score with the POWERbreathe challenge. The highest score was 184 cmH2O for the men and 93 cmH2O for the women. Please see pictures attached. Also these guys did a promotion with the Eurosport channel throughout the Olympics where someone had the chance to win a POWERbreathe Plus every day for answering the questions correctly.
