When you can ride entire packs of cat 1s off your wheel and drop them at age 17 or so because of innate talent there's no need nor any opportunity to develop pack riding skills in actual competitive situations. | |

Chung | On Ferrari's old 53x12.com site, he talked about Rominger's "prep" for hour, and said that at Indurain's speed, Rominger would have only had to have produced 413 watts. Extrapolating from that to Rominger's actual speed would have produced close to the 462 watt estimate. | |

| Mar 7, 2022 at 11:51 | comment | added | R. Chung | Indurain was very inexperienced on the track, crashed in practice, and was reportedly skittish during the official attempt so may have backed off from his max sustainable power. Also, he reportedly couldn't hold the black line so certainly went farther than the official distance. | |
| Mar 7, 2022 at 11:51 | comment | added | Chris H | @R.Chung the discrepancy between the 2 papers is interesting, and reinforces my point about error margins. Padilla and Basset should be using the same data, but Boardman differs by 3%, Rominger by 6%, and Indurain by over 12% between the 2 papers. The difference in Indurain's power is ~17%. Strangely even the weights don't match, so it's not just an artefact of how they handle the averaging of their power data | |
| Mar 7, 2022 at 11:44 | comment | added | R. Chung | Here's Padilla's paper on Indurain's hour record: pubmed.ncbi.nlm.nih.gov/11007591 He says Indurain was 81 kg, and gave 509 watts as Indurain's hour power, though that's his lab measured value, not the power during the attempt itself. | |
| Mar 7, 2022 at 10:39 | comment | added | Chris H | Thaniks @R.Chung, good spot, and I've got journal access here. Handily that has body weight as well (even if there is a typo in the header for the mass column). Using those figures, Boardman comes in at 6.5 partly due to a lower weight than I found, but in 1994 Indurain is 5.6 and Rominger 7.4! | |
| Mar 7, 2022 at 10:25 | comment | added | R. Chung | You might find some of the data in table 7 here useful: they give estimated power and mass for several hour records from 1967 to 1996, including Indurain and Rominger. In that table Boardman's 442 watts is reported as measured rather than estimated. pubmed.ncbi.nlm.nih.gov/10589872 | |
