On Saturdays I try to go for a 20+ mile ride and I take a break on Sundays. Since my endurance and speed are increasing quite rapidly I would like to know where is a good place to keep as my comfort zone?
I just want to get a little more fit.
Try this from Dr. Kenneth Cooper:
65% of your Maximum Heart Rate (MHR) for a minimum of 30 mins and work your way up on time duration.
Your MHR per minute = 205 minus 1/2 your age
EG: 60 years old cardio workout would be = (205 - 30) x.65 = 113.75 or 114 beats/min heartrate for a minimum of 30 minutes.
Try that pace for 30 minutes and recover. If you have more in the tank get the heartrate back up to 114 beats/min. and repeat the process. You'll be amazed how strong you will get over time.
This is how they get cardio patients back up to speed.
Hope this helps.
