The reason for @GuyBoden starting this thread and posting that comment is that I had warned him of 15-20% ramps on the route we would be taking on my Scammonden ride. We did it yesterday. I am sure that he would be happy to confirm that RideWithGPS had got it wrong and that I had got it right...I find it very disconcerting that if you plot a long route, a stated 10% max gradient could in reality be a 20% max gradient.
It tends to be closer on normal rides perhaps the garmin can't record fast enough a some speeds

Put a clinometer on the bike:How else are you going to measure it?
I've just checked Plotaroute, and it quantises at horizontal increments of 90m.Depends how granular you want to get with your gradients
That reminds me of the day when I walked from Oxfordshire to South America and back again.I haven't done this segment since I got my Garmin.

I wonder what it will register during the near 800 feet vertical pitch?
I have a group social ride coming up later this week - the organiser sent out a GPX file that I imported into Wahoo for use on my GPS unit on the day. It might be a bit beyond me though...

I had exactly the same thing at the weekend. I was going up a typical Kent hill which is in a deep chalk cutting. I must have lost signal for a short while. I glanced down at my GPS and it was saying 26%. I thought "it's steep, but it's not that steep". No, the max gradient was not 38.4%

If I look at the same stretch going downhill (where I didn't lose signal) it's actually about 500m long (so I lost 200m when I had no signal) and has a max grade of 21%. It's definitely steep. But not vertical.
What hill is that?

😂🤣 I’m sure it can cope with someone on a bike. It will record once a second regardless. Unless you’re approaching the speed of light on your TT I don’t think it’d struggle.
"Accurately measures the steepest of hills"... but it only works to about 20%!Put a clinometer on the bike:

Indeed. The steepest hill I ride maxes out at about 33% - fairly short, but still a real brute.
