Participation in ultra-endurance events continues to rise, with more events added to the calendar yearly. The largest cause for non-finishing such events, are issues originating in the gut, with symptoms including nausea, cramps and diarrhoea. Following successful studies with Challenge Barcelona and this year’s Marathon Des Sables, sports scientists at Anglia Ruskin University Cambridge are now researching the cause and the effect of probiotics in maintaining gut health while undertaking such ultra-endurance challenges.

The research team led by Craig Suckling and Dr Justin Roberts are currently recruiting volunteers for 2 laboratory based studies, one starting in late August 2015 (in the build up to the Ridgeway Ultra race in November), and the other in early 2016. They are looking for any recreational athletes aged between 18-60 years, in good health and who train at least 3 times a week. For more information or to participate in the study contact

Please note the deadline for expression of interest for the current study is 15th August.
The closing date for expression of interest into the second study will be December 15th 2015.
