Exercised induced diarrhea?

I am 67 years old and play tennis three times a week.  Never had a problem.  Six months ago I was doing some longer distance bike rides, generally around 30 miles a ride.  I did 58 miles and a 67 mile ride.  No problems.  I drink atleast 2 liters of water during a ride. Over that time on three occassions after about a 30 mile ride I had servere diarrhea and once with severe vomiting.  I stopped bike riding a couple of months ago because of it.  Today during a tough tennis match after the second set I started to experience diarrhea symptoms and could not continue the match.  I also experienced shoulder/neck aches.  This had never happen before.  Normally I can play 3 sets and over 2 hours of tennis without any physical discomfort. I try to keep well hydrated during my tennis.   I have had my heart tested with good results.  I do have a thyroid condition and take medication diligently. (L-Thyrox 125 mcg 125).  I have Hypertension and take Lisinopril 20/12.5E152.  I also take Lovastatin 40mg.  Thanks John

The drug Lisinopril is probably doing this to you, as feeling flu-like, diarrhea, and vomiting are some of the side effects.  You need to visit your doc and get on a different drug than that one.  Just Google search that word from your home page and visit some of the websites that come up, and they will give you side effects, to confirm what I am saying.
