My race predictor has gone wild over the last few weeks with my estimated 5K time ranging from 16:05 to 17:30 and fluctuating all over the place. For example after my run on Tuesday it tells me my prediction is 16:30 then I do a gym session in the evening and the prediction rises to 17:30. How do I lose a minute?! During this time I have ran a 5K in 15:56. What is causing the wild changes and inaccuracy?!
