Another failed attempt at Garmin Lactate Threshold Test

Probably not the best day to have another go at the Garmin Lactate Threshold Test, given that I am experiencing the back-end of a cold, however I thought I would have a better chance on my treadmill.

At first, I couldn't work out how to do the test on the treadmill as it is simply not an option under 'Virtual Run', or 'Treadmill', but only one 'Run'. I should have really turned the GPS off and selected run indoors (next time).

Anyway, the test kind of worked - I was running within selected heart rate zones, however like last time, I blew out on the penultimate set, and didn't complete the last 166bpm+ set.

So my zones remain the same for now. Garmin has them down as

Z1: Warm up 112 - 130bpm

Z2: Easy 131 - 148bpm

Z3: Aerobic 149 - 153bpm

Z4: Threshold 154 - 165bpm

Z5: Max. 166bpm +
