Good morning - I'm also 97kgs and a MTB'er. Also with exercised induced asthma. Been having it since I was 4. Should not be an issue I ride with a inhaler - various brands: ventolin, asthavent, venteze - latter 2 is about R25 each and can be bought over the counter. I use it before I go on a ride as prevention and then its in my backpack for an emergency. I do find that my asthma is less of an issue the fitter I get. At the age of 41 i discovered a chronic pill called Singulair. You buy then on prescription in packs of 28. You take 1 pill in the evening and it virtually eliminates any asthma related symptons for 24hrs - I experienced the effects in 2 days! I know people who use it very successfully for sinus as well. The generic versions of Sigulair is Tropaz (Dr Reddys) and then there is another one. They are about R280 for a 28 pill dosage. It drasitically changed my approach to managing asthma and it feels wonderfull.
