https://t.co/fLNmyY0rTZ Fantastic project to be involved with. Combining a passion for aerodynamics with cycling. What a fantastic machine @JLaverackTi have made - cutting edge in so many ways. @lborouniversity

Recent @lboroalumni Axel Dopfer smashed the prestigious German hour record with the help of @LboroEng and @LboroSSEHS researchers 👏

Alex cycled 51.755km, beating the decade long record.

@lborouniversity @lboroalumni @LboroEng @LboroSSEHS @LboroSport @SSEHub @Vorteqsports What a great project to be involved with. Bringing together my love of cycling and aerodynamics whilst learning new things about athlete performance. A great team at @lborouniversity and big thanks to @SSEHub and @Vorteqsports.

Looking forward to welcoming the #PedalForParis team to @lborouniversity. Small steps can lead to big results in becoming more environmentally sustainable. @Sport_England

[Sport England @Sport_England]

Getting ready for Day 2 of #PedalForParis! 🚲

Today, @Chris_Boardman will be calling in on @PaddleUK to explore the risk of water pollution to its sports, then on through the East Midlands to Loughborough.

@kbergintaylor @TudorProCycling Great opportunity to work with some really forward thinking people.

My calculations were based on Stage 15 of the TdF - Plateau de Beille. I took the average values for Pogačar - 15.63 km, 7.9% in 40 minutes. Yes, the gradient and speed varied, and yes, he didn’t get a draft for the whole climb, but the numbers are enough to show it is important.

Uphill drafting?

Several pundits have asked how much drafting helps uphill. Enough to save 5% of the riders’ effort. 20-25 watts depending on mass, speed and gradient. Absolutely enough to make a difference. Shows how important those mountain domestiques are.

How did I work this out? If you want to get into the science have a look at the excellent research of Thijs van Druenen and Bert Blocken (https://t.co/2tJyqKdPO3). I had the pleasure of meeting Professor Blocken at last week’s International Conference on the Engineering of Sport.

[Duncan Walker @adwalker71]

van Druenen and Blocken show a drafting rider saves about 55% in terms aerodynamic drag. Being proportional to speed squared this is dwarfed on climbs by the effect of gravity. However, elite cyclists are as light as 60 kg and ride at amazing speeds so aerodynamics is in play.

A great evening helping @Lboro_Cycling 's Axel Dopfer (@ADopfer) get more areo at @SSEHub. Thanks Jo Simpson (@Josimps24342584) for helping make this happen. @LboroSport @LboroEng @PaddyTHarrison @Dr_DaveN @LboroPR

[Duncan Walker @adwalker71]

@SHFaulkner Been there too. If it’s aerodynamics I’ll review it.
