I’ve been using the Garmin daily suggested workouts for about a month or so now and have been enjoying the various types of runs it suggests, however I’d had my watch set to “pace” where the workouts are based on pace, instead of heart rate. I’d read that people have had a lot more success with the heart rate setting so thought I’d give it a go today for a tempo run.

What I struggled with was knowing how fast to run to keep my heart rate in the right range. When I started the run, I was under the range for a few minutes until my heart rate came up, then the same again when I started my tempo run. Then I ended up going too high (although I blame a bloody big hill for that!). And then I kept getting warned that it was too high during my cool down segment.

I ended up with a training score of 40%, where normally I’m about 90% on pace based workouts. How do people manage this to be more accurate? I’d like to get the most out of it but a bit conscious that I’m not doing it right.
