Arthur's Seat Challenge (was Gloat)
How fast can you climb from St. Margaret's Loch to Dunsapie Loch on Arthur's
Seat, Edinburgh on a bike (or human powered vehicle for those on the dark side)? This unusual charity bicycle challenge has no date or time limit. Simply visit http://www.arthursseatchallenge.co.uk/ to find out how to take part. Each participant automatically generates £2 for the Marie Curie Hospice in Fairmilehead, Edinburgh*. Tom Orr * to a maximum of 25 participants (unless I can squeeze more money from the site sponsors). |

There are no (big fat zero) suppliers in Edinburgh. Get a folder instead! Did a brompton recently win a commuter chalenge in London? |

Did a brompton recently win a commuter chalenge in London? Well the first two times listed are at the omygod end of the time scale I was expecting so I suspect electric assist would be one way of beating the top time. Yes, I think A Brompton did recently win a commuter challenge though I can't remember where it took place. Tom. |

Well, Hamish Indurian is clearly taking the **** and isn't a valid time. 783W for 3 min? I think not.

Yes both times are very fast which is a bit offputting I think. I have cycled the route hundreds of times and I don't think I am giving anything away when I say that the prevailing wind is almost always an advantage. In a howling gale (not that unusual in Edinburgh) the climb is actually much easier. That is why I think these might be real times. Tom. |

The first time is reasonable, if fast, however 783W for 3 mins is too high to be real I'd say.

The high estimate may be a result of my Javascript formula which gives the power output as: 9.81*w*10*(1191/t)/100 where 9.81 is gravity, w is weight of bike and rider in kilograms, t is time taken in seconds, 10/100 is the gradient and 1191 is the distance in metres. I have not factored in wind resistance (or assistance) or friction and I have distance=displacement which I think may well be wrong. But it is only a rough estimate of power output. If everyone uses the same formula then at least it is a comparative measure. It does show that a slow heavy person has to generate a lot more power than a small fast one. I think the 3m 6s time is the most remarkable. I am hoping for some good times in the next week or so. Tom. |

If you look at http://www.compbio.dundee.ac.uk/~dmamartin/arthurs.png there is a route profile traced from the OS map. The profile is 1.21 km long and rises from 38 to 121m. So your power calculations are a bit off (too high by at least a fifth). ...d |

Tom Orr * to a maximum of 25 participants (unless I can squeeze more money from the site sponsors). The site looks good (I'll submit a time when I get back from holiday). One thing though: On the training tips page, the description of the suggested training ride using a high-gear and mashing, should be prefaced with "If you hate your knees...". Far better to see how many reps of the circuit (~3.5miles) that you can do. Your strength will naturally increase, but you legs will still be able to bend 10 years down the line! Jon |
