The Vysočany Clarion Congress Hotel Prague has for the second time supported the MARS – 24-hour MAraton s Roztroušenou Sklerózou (Marathon with Multiple Sclerosis). The sixth year of the non-stop physical training event to help people afflicted by multiple sclerosis took place from 3 – 4 March 2017 in Prague and another almost 30 Bohemian and Moravian towns. The objective of the marathon’s information campaigns is to draw attention to the issue of the disease itself as well as highlight the importance of physical exercise and a healthy lifestyle for patients suffering from multiple sclerosis.
