Each week I will feature a swim, bike, run, strength, core, or flexibility workout.
There is no better test of your inprovement on your bike and fitness level than a Time Trial (TT).
Either find a route outside that has no (or as few as possible) stop lights, stop signs, traffic, wind, etc OR ride on an indoor bike (make sure you use the same settings, levels, etc for each TT).
Pick a distance you are able to do once a week or once a month to test your improvements.
Write down the time of day, how you are feeling, stress levels, and what you ate that day so you can replicate your subsequent TTs as closely as possible.
Record your time, perceived exertion, heart rate, etc after each one to compare date. I like spreadsheets :)
