Hi there,
For about 2 weeks now my pace when running is bonkers. Ranges from 4:50 up to 8:00 and everything in between, constantly (one second it's 5:00, the next second it's 6:20). It's driving me nuts. I know my pace is consistent. Is there anything I could try, or should I return it for a replacement (bought from Amazon in January). I've lost all faith in this one. (It did an update pre-today's run).
TIA
