First of all, I'm not talking about a corrupted/damaged file.
During races and enduranceruns my autolap is set on 1 km. But sometimes I accidently press lap or stop on my watch. Then I get for example at a certain moment a lap of 500m followed by laps of 1 km. But those laps of 1 km don't start after excatly X km but after X,5 km. I would like to see every km start after an exact rounded number of km. In my excel-file where I keep my training I solved this partially. But this assumes a constant pace and HR for every lap. For example if I ran a km in 5' after I accidently pressed lap excel will add2'30" to my 500m lap. But it might bepossible that I in reality ran the first 500m in 3'. Is there a tool to fix this?
