I was fortunate to be able to spend about 7 hours a week on physical exercise when I was racing. My family was very accommodating for this, but my modest physical talents did not justify any more investment. I never felt the pull for Ultras or other endurance events. At 62, I think I still maintain the benefits of fitness with moderate varied exercise, with no training or racing calendar ruling my life. I've been able to scratch several other deep long term itches after I stopped racing.
