Using Workouts

Today I created my own workout and then completed that workout.

Where do I see the data from that workout?

It has gone to Strava but not with all the interval data.

Also please can you explain the 'Zones" e.g. Z1 Z2 etc

Here a a good site that can help you with workouts.

Strava don’t show interval data, I use sport tracks to analyze and store my data.
