My triathlon training requires me to practice and train in open water which is usually a dock, lake or reservoir. I wear a wetsuit (which is the correct fit) but despite increasing my Seretide 125 to 2 puffs the night before and on the morning and then also taking my Ventolin before any training I still wheeze badly the whole way around and it's really affecting my performance and confidence. The problem is the compression combined with the colder water as once I'm out or in a normal pool I'm absolutely fine.
Any tips please on controlling asthma during open water swimming when wearing a wetsuit?!!
