I am a 63 year old male in reasonably good physical condition. I am thinking about entering an AARP
triathlon. It is 300 yard swim, 20K bike, and 5K run. I am looking at the times in the events that
have finished and I am discouraged with how poor my performance would be.
I enjoy outdoor exercise. In a typical week I ride my bike 2 days at 20 miles per day, I swim 3 days
at 22 laps per day, and walk (mountain climb) 2 days at 6 hours per day. My resting heart rate is
50. I have done Grand Canyon to the river and back as a day trip. I have very good endurance but
poor speed. My maximum heart rate is 153 on my bike.
On bike my average speed is about 8.5 MPH. I tried 12.4 miles and at a heart rate between 130 and
140 I was able to average 11 MPH or 1:12 for 20K. In my age group the Beginners finish times
ranged from :36 to :57. In swimming I have endurance but not much speed. It takes me 2 minutes per
lap. My 22th lap might be a slight bit faster than the first. 300 yards takes me :12. Finish times
for my peers was :07 to :15. I would have been 14th out of 15. Overall I estimate my finish time
would be 2:12
vs. 1:11 to 1:59 for my peers. Am I really that much slower than my peers? My normal exercise looks
similar to recommended training routine. How much improvement can I expect?
