Joe Goldberg Working hard
Map a 3-mile route that you can ride without stopping. Strap on a heart rate monitor, warm up for 20 minutes, then ride the route at the fastest pace you can sustain. Recover for 10-20 minutes (ride back to the start of your route at an easy pace). Repeat the test. Your LT is 103 percent of that figure (HR * 1.03). Jot down your times and average paces; repeat the test in eight weeks to see your progress.
