I want to split this race into 5 laps, but none of the tools to add intervals are working for me. When I press A, a band briefly shows up but then disappears.
When I try the trick to “Clear all intervals” I get this error:
Am I missing something? I don’t have power or heart rate data - do I need that to create intervals? I just want to see average speed for each of the 5 laps.
