If it's anything short of high-resolution, frequently reported GPS then it's unlikely to catch the high but short-lived instantaneous speeds you get on urban roads. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19616#post-307272 Wed, 22 May 2019 14:17:29 +0000 Frenchy 307272@http://citycyclingedinburgh.info/bbpress/ <p>That would be useful.
