I have done quite a few HMs with my Garmin and it can come out anything from 12.9 to 13.8. Average variance is around 2%. I don't trust the pace readings during events for this reason and prefer to work from HRM readings and splits at mile markers. All to do with domestic GPS being fairly imprecise, esp in built up areas.
Have entered and got my number back, but without any info on the 10m race at all. Event website doesn't fill in many gaps either, eg changing facilities, car parking, course map, first aid. Have emailed organiser, but just wondering if this has happened to others or if it's just me?
I have a Garmin 301, bought in 2005, and have found that it tends to read distances short. In four half-maras over the last 6 months it has recorded mile distances of 13.49, 13.18, 13.11 and 13.61. It seems to make no difference whether the run is urban or rural; the 13.61 was from Taunton half-mara last Sunday.
So the average variance is about 2% off, which doesn't sound too bad until I realised that when the Garmin says I'm running at my target pace of 06:48 per mile, I'm actually running closer to seven mins per mile. Not too bad in an event, given all the mile markers that pop up 100 yards after the Garmin beeps out another 1m auto-lap, but a real pain is for speed-endurance training and trying to work out how fast I'm going in training.
Anyone else get similar discrepancies, or a Garmin that reads longer than actual miles? Or is mine just bust?
What Hoo! First post in yonks, so yurr tiz. I run in specs and wear a baseball cap in the rain, but it's not very effective in winter when rain is horizontal. If I took them off I still wouldn't be able to see anything, so it's 6 of one etc. Despite the tendency to feel like a goldfish, the disadvantages of wearing gogs are far outweighed by the advantages of running in the rain (no dog walkers, no hecklers, no families all out for a bike ride together, and I get to jump in muddy puddles for miles on end)
I also wear prescription sunglasses when it stops raining. I asked how much prescription Oakleys were, laughed heartily at the number I was told, and then promptly got tinted lenses in a frame I already had, which was quite expensive enough. One useful feature of these is the arm thingies down the sides are sprung; they really grip the side of my head and don't slip at all (but do leave a deep mark).
I've never tried running without glasses; too afraid of running into things, like dogs or children, or jumping into a puddle only to find it's roadworks.
