How fast do you need to go for a social ride at York Show?

Went out with a GPS speedo the other night, and down-rated my cycle
speedo by a few percent as a result. I'm not sure if the GPS is a little
pessimistic, especially if it loses its signal. It saw a moving average
of 10mph on varied hillyness. I wasn't pushing it by any means, and I
was also exploring and finding new routes, but I'm sure I used to cycle
somewhat faster.

Problem is, does a paltry 10mph disqualify me from the social rides at
York? I remember hearing that the year before they went quite fast. Last
year I didn't take part in any of the rides.

The CTC Saturday "A" ride here averages 12-13mph. The "B" ride is quite
a lot slower.

The local road club average nearly 20mph, touching 28mph on the flat,
but they're nuts.

I'd trust your cycle speedo over the GPS especially if it has been calibrated
with a roll out

I'd started with a roll-out, then did a measured 10 miles and checked
measured distance against the map, and applied a correction factor. I'd
not rechecked it though. Perhaps I ought to. The GPS is meant to be
very accurate, assuming steady state. The software seems to do some
averaging. If you take a sharp turn, your GPS track continues in its old
direction for a second or so. This made direct comparison quite difficult.

Anything less than 24.7 mph average over 73.67 miles marks you out as a
wimp who must not even contemplate sitting in the gloriouis saddle of
imblegentiousness, and should seriously contemplate self-mutilation of some
form, preferably involving a turnip.

Morrisons to turnips - would that be the purple veriety or the spotted
pink ones?

You'd have trouble measuring a map to few percent. The GPS does positional
accuracy reasonably well these days but speed and distance have various
errors. Distance as you noticed because it only logs position at regular
intervals so approximates the curved path as straight lines and speed because
either it does inaccurate distance over time or doppler on the satellite
signal, both of which have errors.

Purple on the way in, spotted pink on the way out.

To answer the question: no, you'll be fine.

Don't go on the 'Fast' ride, or the A one. They are indeed fastish. Their
are shorter/slower riders are well. Have a word at the info tent the night
before or with the ride leader on the morning.

If you can do 10mph on your own and feel you can go faster you should be
ok for a group ride at 12mph and there's a couple of suitable rides at
the rally next year.

I won't be there for the first time in a few years, but since that's because
I'm off to the alps, it doesn't seem too much of a shame!

I am considering doing my own thing, none of the rides appeal to me at the
show, partly as I want to go for a 70 miler and partly as I regularly ride
some of the roads around York. Thus I am thinking about a ride out to the
coast for some sea air.
