This year, Prion Laboratory was involved in a project Bike to Work, which aims to encourage the public to use cycling, walking or running as a regular means of transport around the city. The five-member team PRSK (PRionová SKupina) led by the Head of the laboratory, Dr. Holada, cycled 1800 km in total during May and with regularity of 81.5 % completed trips ranked 170th place among 988 teams that competed in Prague. We will definitely participate again next year, join the project too!
