Cycling for MCS

Why are we doing this?

Multiple chemical sensitivity (MCS) is a recognized disability in Canada. However, people experiencing MCS are left without any support system and face challenges in receiving and accessing healthcare services adapted to their disability. For example, most hospitals don’t have a “scent-free” policy.

Moreover, although the number of MCS cases is on the rise, going from 2.5% of Quebec’s population in 2015 to 3.4% in 2020, most people have still not heard of this health condition. In that context, Olivier Chabal will embark on October 1st on a 24-hour, 500 kilometers cycling challenge in order to raise funds and awareness about the issue.

The map below features the trail map Olivier will be taking on that day and the timeline of his 24-hour journey:
