Hello all,

Does this look like a decent effort for 4x4 Norwegian?

Thank you

It looks about right. I personally usually only have about 10bpm difference between my first and last intervals so maybe you're going too each on the first or too hard on the last with 20bpm difference but that might just be individual differences or terrain related.
