Amashova 2018

[CatchMeIfYouCan]

So by my calculations, comparing 500th place, 1000th place and 2000th place to last year's times it would seem like everyone was around 12 to 13 minutes slower than last year for the same finishing position.

 

Sounds about right. Ran a few calcs and this is the % of finishers achieving a "Sub 3" time: 

 

2016: 12,67%

2017: 11,81%

2018: 7,83%

1.1 BETA for that wind?!

 

I know it is an algorithm that calculates the BETA, but that thing must have had some Durban Poison while it was down there doing the calcs. Was definitely infinitely more difficult than 947 with a 1.24

Interesting.  While I did not ride the 947 last year, so can't speak for that, when I apply the 1.10 BETA to my time, I come in at 2h57 which is bang on what I had originally hoped for.

Was also shocked to see a beta of only 1.1. What was the beta of last year's race?

 

CL group was absolutely mad. Okes at the front going up every hill at like 5w/kg for the first 35-40km which was where I got dropped. Then it was a long, painful ride in small groups with the bloody wind.

 

Back to the difficulty, as a reference, last year 49 people from CL did sub-3. This year 6 people did sub-3.

So you guys had a nice relaxing ride?

 

AL pretty much was that the whole race - I also don't get the beta... I think it was harder than the rating... but then the winning time was 2:22 from 2:21 last year and 2:20 in 2016... even AL was 2:44 in 2017 and 2:47 this year... so maybe they did not think the wind etc made that much difference.

last year was 1.11 beta.

 

they do use the winning time for the beta, and usually weather conditions. A few years back they adjusted a few race beta's months after the event, so maybe someone will take it up and have them change it.

The way I understand the beta is that they use everyone's (who have done a specific reference race as well) finishing times compared to the reference race to get a relative difficulty (i.e. beta).

 

So what I really don't get is how a race that was demonstrably harder (see attached graph) gets the same beta as the race a year earlier. Does anyone have a contact at PPA who can explain this?

Anyone that can give me ONE good reason to do the 100miler?

It is a 100miler!

That would be a bit of a miscalculation, considering mt experience of bunch/wind riding skills in CTN. Look at the 1st 100 to 200 max to compare. After that it is a mixed bag an most cant hold a wheel, sit slip etc. So if you are comparing indexes the lower down the bigger the difference will be.

Man I love graphs! That just shows it so clearly.

FWIW, I enjoyed the descent from Hilton down the Sweetwaters descent on Saturday last week. Sneaked onto the top 30 on the Strava leaderboard, although about 10% off the leading time. Knowing a few of turns I guess does help as does a traffic-free attempt. Guess it will have to wait for another attempt next year.
