Seems correct to me

Distance : 11.3 Miles
Time : 38 mins 12 seconds

so your average equals 17.74mph

38mins is the moving time calculated by strava. The actual time of the ride was 46mins. The difference between the average speeds calculated will probably be due to different ways they detect moving time vs stopped time.

It's just the way Strava measures things (including moving time) indeed. However, my Garmin data that use a speedometer regularly reads 0.5mph or more higher than Strava works out. I've measured the wheel/tyre too.

My Garmin and Strava times and speeds match exactly and always have.
Do you have your Garmin's setup properly?

Yes I do. As I mentioned I have measured the wheel/tyre and have input that data into the Garmin.

Do you use a speedometer?

edit: I see you've added examples. I'll grab some too.

Older examples had more of a difference. I'll see if I can find some.

Still can't find anything as extreme as I've seen in the past.

I dont bother putting stuff on garmin anymore. I'm not really bothered about average speed anyway, power or heart rate are much better ways of gauging effort.

For your rides, if you dont actually stop there isnt much scope for the different programs to calculate stopped time differently :p

I use a Garmin Edge 500. My road bike has the wheel magnet and cadence sensor fitted and my MTB just uses GPS to calculate the speed.

The stats for rides on etiher bike match when they are uploaded to Garmin and Strava.

I plug my Garmin in and G Connect and Strava are updated automatically through Garmin Express.

I should have clicked on analysis :p Yeah. Obviously not stopping will affect things somewhat...

edit: I just have my Garmin upload via bluetooth at the end of each ride. It automatically syncs to Strava after that.

Yeah - those are pretty much spot on.

By the way, I was going to ask. Your average number of rides per week is 24 !!! Just curious - Why so many short trips?

They're out by 0.2/0.3 mph but yeah, nothing like as bad as I remembered.

I commute plus at lunch I will usually cycle home too. The routes vary depending on how much time I have/how knackered I am but generally I try to get as many miles as I can fit in. I got into the habit of recording them as separate rides when using the Strava android app (partially so I could log the miles as kcal earned for my dieting and partially because the Strava android app used to be a bit unreliable at times). On top of that before it got so dark in the evenings I would often go on evening rides and usually a couple at the weekend.

I could reduce it all down with pausing and such so it just said 7 rides per week but at the end of the day they are all separate rides with a few hours between them. I guess it's probably kind of annoying for people that follow me on Strava as their feeds get cluttered up but meh.. they can always unfollow me :p
 
Holy mackerel, yesterday ride was horrendous! i was so slow. It was wet going through the Chilterns so that didnt help but thats no excuse. My form was terrible.

Now winters here im going to bring my bike in to work and go out for an hour at lunch. The 5 weeks off for various things has killed me! still it was nice to be riding again:)

Bluetooth upload is pretty much essential for you then, else half of your day would be uploading activities :p

The monitoring/checking I did before lead me to conclude that Strava is much more of an estimate than anything else - it has to use GPS to gauge your speed. It has to use GPS to gauge when and where you stopped and for how long. It then has to use GPS to plot on it's map the route you took and then calculates everything together. There's a lot of calculating done on probably very vague data (ie how accurate GPS is from your device and how often it's read).

My rides taken with IpBike (on the same device) should have been using the same GPS data, but distance and speed were calculated from my Garmin GSC10 (speed and cadence) making it much more accurate for speed and for any movement/stopped times. I upload the data to Strava anyway and it changes (I'm guessing Strava do their own calculations on the data just the same). I found regular differences between the pure Strava recordings compared to the IpBike ones - my total distance was different, total time was different and I assume the stopped times also were. Same bike, same ride, same device, different sensors/calculations.

I'm the same, a ride is a ride! Times when I go to a shop on the way home I generally stop and then do a new ride when I leave. Although if stopping to post something I just pause...!

You're not a pain to follow on Strava, but I naturally filter (using my brain) peoples commutes and pickup the non-normal/regular/longer rides ;)

Felt strong this morning (woohoo a 3rd PB!) which is quite unusual for me at the end of a commuting week! (rest day on weds). Not sure about the temperature reading lol
