The 2025 Half Century (50km or 50 mile) Challenge Chatzone.

I 'broke free' during the Covid pandemic and haven't really fully got my longer rides mojo back since! It is good to enjoy shorter rides as well though.

Has your bike got an accurate power meter on it, or is your power data estimated by an app?

I ask because your displayed power is about 30% higher than what I typically manage. I can quite believe that you are more powerful than me (you are younger and bigger than me, and I am not superfit) but...

... if I could generate that much power I would be going even faster than 15.4 mph on roads with far more elevation gain. For example, on a ride with over 1,500 ft of elevation gain I averaged around 14 mph but I only averaged 182 W (measured to within +/- 2%).

Obviously, the distances and speeds displayed in your posts would be very accurate, so I am wondering if the power value is 'guesstimated' in software?

Just whatever Strava spews out with my bike weights (This one is pretty heavy !), my weight (Nearly 16 stone), height etc entered in - and kept updated.

I’ve done nothing to modify, look into, check those against anything else or otherwise…..

I would trust that power value if you did that speed on a hilly route where your weight would definitely be a significant factor, but extra weight doesn't make much difference to average speed on flatter routes.

I am not knocking your efforts; I was just curious to see where the numbers came from!

Could someone here with experience of riding with a power meter tell us how the real data compares with what Strava comes up with? (Or does Strava only guess the power when power measurements are not available?)

My plethora of pictures tells you why I ride 😁 Speed, calories, watts or anything else are extremely secondary…

In saying that - my power output does often seem to be high compared to others doing similar speeds / distances. *I never really pay much attention to elevation. Certainly in cross referencing. It’s not something I can remotely control or change. Not sure why this power stat appears to be so ‘different’ 🤷‍♂️ as I have all data Strava asks for: entered correctly.

Just as well I’m not basing anything on those hey…….. 👍
