Many people with MS take part in Ultra Challenges without any problems - while you are able to tackle this event at a pace that works for you, it can still be physically demanding, so you do need to be generally fit and have a good level of mobility. If this trip isn't for you, perhaps you might be interested in one of our other events such as Miles for MS.
