Do you bike train with a power meter?  If you can afford to get one, I strongly recommend it.  Heart-rate is ok, but it’s decoupled from the level of effort you’re putting out and just time and perceived intensity is way too subjective.

If you are training with a power meter, I encourage you to checkout Golden Cheetah: Cycling Performance Software for Linux, Mac OS X, and Windows.

It’s an open-source analytics package for cycling power data.  It provides a LOT of great information AND it’s FREE!
