Hi,
On 8th March 2014 I ran 21.45km in a time of 1:54:43. On 23rd March I ran 21.28km in a time of 1:53:28.
The latter time appears (due to a km by km comparison, average time etc.) to be faster. Both qualify as a half-marathon, and yet Garmin does not recognise the latter time as faster (and hence a new personal record for the half-marathon).
Why would this be the case?
Thanks
