Warning! Maths (no not really, it's just running, you can relax)

[Yesletsgo]

Over the last two days I've done a lot of driving - Essex to north London to Brighton and back to Essex. The car is manual, so all that clutch work and sitting still for hours did my bad knee no favours. I woke this morning with aches and knew I needed a run. The issue: I really want to do Parkrun tomorrow and I don't normally run two days in a row.

The solution, a short and gentle recovery run. The sun was shining and the thermometer said 7C. For once I got the clothing right, short sleeved top and warm leggings so no faffing around taking a jumper off today

We decided on 3 km. The path was muddy and slippery in places, so lots of hopping from one side to the other to find the relatively dry grassy bits. The sunshine was just warm enough, a perfect temperature, and I'd put a cap on so that the low rays didn't dazzle me. It's wonderful to be outside.

We passed the halfway point and turned back. My husband said, 'Let's do a pi run' (3.14km). He uses his Garmin watch but only measures his run, while I use mine for the warmup/cooldown walk as well so can't use it to see how far I've actually run. I use the NRC app for this but it doesn't show how far I've gone when I'm out running until I pause it (need to look at the set up lol). It's much easier to for him to measure his distance run.

Anyway, we reached 3 km, then he got to 3.14 km. I checked NRC - 3.10. Ran a little bit: still 3.10. Ran a bit more: 3.11. Ran quite a bit: 3.14! Hooray! Pressed stop. The display now said 3.15km. Much gloating from the other half....until I checked Strava. This shows 3.13km for him.

So on average, between us we ran 3.14 km - a 2πrun (shoulda run in a circle 😂)

PS I tried to find a picture of a running π symbol but I could only find pictures of Raspberry Pi computers

PPS apologies, I'm a bit of a geek sometimes

Loved this 😊 It did take me a while to work out what a Pi run was 😂😂Sorry to hear that your knee problems have been aggravated by all your driving. Hope it settles down quickly

[Yesletsgo Administrator Graduate10 in reply to dijep]

Thanks dijep , the knee is absolutely fine now. The more I move, the better it feels and the run sort of released the tension if you know what I mean? Seriously considering getting an automatic car when the time comes to change, it can get very niggly in traffic.

The tao of running, perhaps? 🤓

[Yesletsgo Administrator Graduate10 in reply to nowster]

Not sure how to do that one but open to suggestions 😂

[nowster Graduate10 in reply to Yesletsgo]

I meant to say "tau". τ = 2π

[Yesletsgo Administrator Graduate10 in reply to nowster]

Thank you nowster , this can be my new fact for the day

Tau is definitely easier to run than Tao 😂

These days I'm better at googling than I am at maths Yesletsgo

Runing pi symbol

[Yesletsgo Administrator Graduate10 in reply to Cmoi]

Brilliant! Just what I was looking for 😁

[Cmoi Graduate10 in reply to Yesletsgo]

All I did was google running pi symbol and it was the very first image result! I worked for an SEO company for a few years, which definitely affected my approach to internet searches and results. 🙃

[SueAppleRun Graduate10 60minGraduate]

Perfect, last time I read of a pi run I asked my mathematician granddaughter about it and she gave me all sorts of maths lessons but sadly it didn't stick very well, luckily you are out doing a pi run so I don't have to worry about it 😄 thank you

[Scruff55 60minGraduate]

ha ha ha. Great report of your 2pi run. Loved it. Well done.

[Beatlesforever Graduate10]

A Pi run. Absolutely brilliant 😆 hope the knee is better x

Maybe next do a γ run (gamma run) where γ=0.57721... (Euler's constant) or a ζ(3) run (zeta 3) or a Π ( n ; φ ∖ α ) run where the latter is an elliptic integral of the third kind.

[nowster Graduate10 in reply to Comte]

There's also the better known Golden Ratio φ = ½(1 + √5) ≈ 1.618

Not forgetting Euler's Number (AKA Napier's Constant) e ≈ 2.71828

[Yesletsgo Administrator Graduate10]

Or follow a Fibonacci sequence over a period - 1 1 2 3 5 8 13 21... (my maths is pretty basic compared to yours guys)

[Leotigris Graduate10]

That Fibonacci sequence looks quite scary - the number start increasing quite quickly!

[Yesletsgo Administrator Graduate10 in reply to Leotigris]

That's why I stopped adding numbers, I was well out of my comfort zone 😂
