There are a number of ways to establish baseline measures for fitness. One easy way is to cycle a self-designed time trial, a TT. This TT can be any section of road, including a climb. Depending on your current level of fitness, begin with a three- to 10-mile distance. After a good warm-up, go as fast as you possibly can on your course of choice. You can use a number of tools as benchmarks. At a minimum, note the time it took to complete the TT. If you have a heart rate monitor, add the marker of average heart rate. Finally, for those with power meters, note the average power produced over the TT course. If you use applications such as Strava, you can create a course segment for your test. Aim to retest every four to six weeks to ensure your training plan is producing improvements.
