I have been recording my blood pressure since 1988, which is 20 years, since age 21. It is common practice to check my blood pressure during bike rides.  On 2/21/2008, during my bike ride to Oakland, my blood pressure was 141/97. On 6/28/1994, during my ride to Gilroy, it was 124/86, on 6/13/1996, during my ride to Sausalito it was 155/95, on 5/24/1997, during my ride to Half Moon Bay it was 174/104. On several occasions my systolic was higher than 200. One time, it was 239/57. On 3/3/2008, I had unbelievable hypertension, 226/98. On 3/2/2008 it was 217/116.
