Watch River Cottage Season 15 Episode 5 Online

Hugh immerses himself in the pleasures of wild swimming with vegetarian triathlete Colin. Meanwhile, Tim and James go head to head in the kitchen with a summer veg showdown. Colin Hill has swum the English Channel, the Bosphorus and the Hellespont, and he puts pay to any suspicion that a meat-free diet lacks power. But his pasta-heavy diet lacks imagination - pasta and ketchup, anyone? So Hugh whips up some delicious carb-loading dishes that provide plenty of flavour as well as energy.
