There's a bug that my first 20sec repeat which i have programmed into separate lap, gets mixed into base run and therefore avg pace and heart rate are not what they should be. from repeat 2 it works as it should. So that "Run 11" should actually be Interval number 2.
also during could weather heart rate gets erratic and goes very high (see km 2). happens with strap as well, even i soke it in warm water before running.
