My HRM lets me program 3 zones, and tells me how much time I've spent in, above, and below each zone. So, I can use this to define 5 zones; the 3 programmed, above the max and below the min. My zones are based on my lactic threshold. I program one zone 89-93% LT (tempo), I program the next 94-100% LT (threshold), and 100-105% (super-threshold). Below 89% is aerobic on down to recovery, above 105% is anaerobic capacity. I don't use alarms and zones during the ride, I mostly go by the current reading and my perceived level of effort. I use the zone data afterwards for evaluating the work-out.
If I had only one zone, I'd program 89-100% LT... that defines the 3 main areas. Below is aerobic, within is endurance, above is intensity.

age 57, my upper limit reachable as 165, but rarely meet it, I Dont set a low limit on the monitor as Occasionally I want to go slow, so this is set to 100. I set my upper limit as 155, but believe me, I know when I am up around this level, I like to ride on the flat at around 140/145, effort uphils to 155, but push on last bits to 160, When the youngsters fall off, or it gets technical, or I am Chasing the youngsters up the hills, I will go to 175, but very briefly. This level hurts.
I can ride all day if I stay at 140/150, and this is the type of riding I do, Offroad riding, plenty of hills, and up to 100 milers, that take around 12 hours to complete. I am not a sprinter,and even at the start of a ride, cannot sustain high speeds for too long.
For my age I class myself as pretty fit, but Am definitely not the fittest around. Especially compared with the relative youngsters at around 40.
