I am an cyclist. I at least cycle about 30 km everyday. Other than, I love playing basketball. I play at least about an hour everyday. The problem is, when I am doing these, I sweat a lot than other guys. My shirt is completely soaked, when others are hardly sweating . Is this is a disorder? Is it hyperhidrosis? I am hoping I am not suffering from hyperhidrosis, because casually I am fine, no sweats. It just happens during sports or similar activities.
I think you are fine. Check out the following articles:
In all three articles sweating as a response to working out is normal. In fact, the body adapts to sweat sooner the more fit you get so it doesn't store the extra heat your body is producing during exercise.
The important caution from all sources is to make sure you stay hydrated. Considering the heavy cardio work you do, a sports drink may be more necessary than just water.
The MedlinePlus link does have additional symptoms to look out for that indicate you should talk to a doctor.
