Was on si.shimano.com and a terrifying idea came to me that one day they might replace it all with youtube howto videos and instead of printing out 2 sides of A4 with diagrams I'd be peeling the gloves off my hand mid brake bleed to skip back three video chapters.

This is a really interesting graph - not just the 800, but the monotonic trends on either side. It's like there's something that has improved "pure endurance," and something else that has improved "pure speed," but their effects somehow diminish when you mix them. Very curious.
% improvement in men's WR running speeds pre-first IAAF WC(1983) to present. 800m 'underperforms'?

This was brilliant and my two (6 and 3) loved it.
If you missed the performances at Camberley Library, fear not, there is still a chance to book at another Surrey Library! For details on the remaining dates and locations on the tour ➡️ eventbrite.com/cc/imaginatio…

Trying to answer what seems like a relatively straightforward question: how many tonnes of CO2 will this car be responsible for emitting in its lifetime?

The big surprise is fuelling costs, which are actually pretty similar between an efficient diesel and the electricity costs at current prices. (Assumptions: charging at standard 34p/KWh tariff (not off peak), 80% at home, 20% on the road. Diesel £1.60/L (has fallen below this)

So that's a bit of a shaky assumption, forecasting energy prices remain the same for the next 7 years, but in the next year or so I would guess that diesel falls in price faster than electricity.

The council apologises for omitting the full stop after 'crocodiles' on this sign at the Municipal Lake, which resulted in 38 bathers being eaten over Coronation weekend.

Current rabbit hole: finding an indoor cycling trainer that is similar enough to riding outside that eg. riding at threshold is at the same power (as measured at the pedals) as opposed to 10-20% lower inside.

I will try the different resistance modes before making a firm decision, but it looks like I haven’t found a solution. On the off chance that anyone reading this knows of an indoor trainer that emulates riding outside very well, let me know.

Tried another interval session, better rested than the last one and sticking with Level Mode (progressive resistance support.wahoofitness.com/hc/… ). This went much better and I was able to finish the session with interval power at 87% of FTP, which is probably good enough.

This matters to me because my use case is, I am an occasional indoor rider and want to ride intervals at threshold / just below but it’s dark/dangerous weather/I’m looking after sleeping kids.
