  1. Hi All,

    This weekend is my big race of the year. I amuse several of my riding
    buddies with often quite accurate predictions of their (and my) times
    over various courses, and now the pressure is on to predict our time
    for this race. Little do they know that all I do is punch in data into
    various online calculators and make some educated WAGs to arrive at my
    predictions. This time I need help with my prediction, so anyone
    interested give me your prediction and your reasoning. Whoever is
    closest wins a postcard (at the least!).

    The race is Trondheim-Oslo in Norway. 540km with 4,400m of total
    ascent. Profile here:
    http://www.styrkeproven.no/upload/2006/loypeprofil/loypeprofil.pdf

    The weather while perfect now is forecast (as usual) to be rain and
    slight headwinds.

    I have done the race 5 times with times from 24 hours down to 19. This
    is the first time I will do the race as part of a team with organized
    support cars, etc. The combination of the positive effect of support
    logistics and riding with a team make any assesment based on my
    previous performances not very useful. And I am WAY stonger now than
    ever before. Our team is looking for sub 15 hours, and if the weather
    cooperates that should be theoretically possible. Last time the team
    (with about 10 of the current 29 members participating, the rest are
    new guys myself included) managed 15:13. That same year a new record
    was set by Rye of 13:28. This year we were 1 hour behind Rye in the
    230km Mjøsa Rundt a few weeks ago.

    Our problem is we may overdo it the first 200km up to the mountain. In
    our group rides the tendency has been to ride too fast and then for
    (almost) everyone to not admit it afterward that they thought it was
    too fast. So I full expect several guys to be used up already after
    the first 200km. I think eating enough will also be a problem for
    many. Our team captain has told me speciffically that I have to let
    him know how I'm doing up the hill because I am particularly important
    for the downhill/flat section from km 200 to 350. I'm pretty sure
    I'll be fine at least to km 450 where the road gets more hilly and I
    will perhaps have run dry. If I have to let go, it will probably be
    there.

    So the team's weakness is sub-optimal discipline, and perhaps too
    ambitious a goal. My weakness is I may have to go too hard in the
    beginning up the hill to keep up, such that I go empty earlier than
    desired.

    How fast will the team manage? Will I hold on to the finish? If not,
    where will I let go and what will my time be?

    Unsupported you averaged 28 kph in a 540 km ride with 4400 m of
    climbing? I find that pretty hard to believe. I assume that didn't
    include the time spend in rest stops along the way.

    The team competition is officially the 10th guy's time. Or maybe the
    cumulative of the top 10, I don't recall. Ideally 13-15 out of the 28
    starters will finish together. The rotation is constant except it is
    locked on hills and in dangerous sections like tunnels and successive
    roundabouts. Ideally at least 24 guys should be in the roatation at
    any time, with that number decreasing as guys get used up.

    Then you will also find it hard to believe that there were over 600
    men and women who did it faster than me. My times were hardly in the
    fast category. The times given include all stops. The race is an
    organized thing so there are food depots ever 60km or so where you can
    fill up water bottles, get bananas, jam sandwiches, and stuff. It's
    not like I had to waste time going into a gas station to buy candy or
    something. The average speed of the winners is about 40km/h including
    stops. Oh yeah, I forgot the winning team doesn't stop. One of the
    reasons they won the last 6 years in a row.

    Here are my split times for last year:

    and here are the splits for the current record holders:

    That kind of puts it into perspective.

    Yikes.

    For team TTs, the pacing strategy is pretty tricky. You have to go
    easier on hills (which you know) and with a tailwind (which you may
    not have), or else you'll shatter your team.

    A constant rotation is very hard to regulate the speed of too. The
    terrain is on for the most part well graded roads, so the yo-yo effect
    is pretty small and we can get a good rhythm going.

    Perhaps the biggest problem is the rather wide range of fitness and
    experience of the riders. The age range is 21 to 62, and the weight
    range is from 55 to 98kg. I don't know the flat 10km ITT times but I
    guess it ranges from 13:00 to 17:00. Should be interesting. We have
    scheduled 3 stops, but we also get bottle hand-offs on some of the
    hills.

    The captain has never been a captain before, but he has ridden the
    race with 2 well established teams several times so he knows how it
    should be done. He has also 2 very good co-captains who know how this
    should be done too, so even though there are a bunch of new guys, it
    has the potential to go smoothly.

    Right now the weather looks like rain and headwinds, temps from 9C to
    15C. The headwind makes things go slower but for my own selfish needs
    helps as it slows things up on the hills. Levels the playing field a
    bit when the road tilts upward. I'm not too worried about getting
    dropped on a hill, just in having to go too hard such that I burn up
    too many calories that I won't be able to replenish and bonking
    somewhere.

    Hills and tailwinds tend to expose and exacerbate differences in the
    abilities of the riders. Headwinds and downhills tend to equalize.
    Combine a hill with a tailwind, and that's bad news.

    dumbass,

    changes in speed exacerbate differences.

    but, can you explain why tailwinds make a race more selective ?

    Tailwinds lessen the advantage of drafting as the components of
    resistance change their relative importance. This means weaker riders
    who otherwise might have been able to suck wheel, get dropped on the
    flats. Tailwinds up hills hurt the weaker riders because they are
    weaker on hills because of their lower power to weight ratio. As the
    speed goes up due to the tailwind, their deficiencies become more
    apparent as the rate of vertical ascent increases.

    Headwinds allow weaker wheel suckers to hang onto stronger riders.
    Tailwinds reduce the advantage of wheel sucking so stronger riders can
    ride away. In a team TT, weaker riders tend to yo-yo off.

    Downhills equalize to a point and only if sucking wheel is acceptable.
    That's why in our team when we get to the 2 real descents, I along
    with another heavy (95kg*) guy get to pull us down. The others are
    probably riding their brakes behind us, but as a group we are going as
    fast as possible. When the road is on a slight descent and we are
    doing our rotation at 50km/h or more I and a few of the other bigger
    riders are just cruising, while I see the smaller riders seriously
    struggling to even pull in front of their guy when they get to the
    front of the rotation. When the road is flat and we are going 40km/h
    they don't have any problems.

    * he has a huge motor since he is a former world class rower, so he
    does not suffer as I do on the hills.

    The team is not optimal, and most everyone knows that, particularly
    the captains. We have spoken about it and the idea is to have a 2-3
    year perspective. This year is more or less to test the setup, and
    have something to build upon next year. As far as wanting to work for
    them, it is by far my best (only?) option for doing this race fast, so
    I'm happy.

    You will hold on, in part due to the headwind.

    In such a situation, the smaller riders could just hang
    onto the back and never go to the front of the rotation.
    Also, you're not really supposed to have to pull in front
    of your leader when you get to the front. The leader
    should pull over and ease up and naturally fall back,
    exposing the second rider to the wind. The second rider
    stays at constant speed (assuming the road grade is
    constant). If the second rider has difficulty keeping
    that speed, he just rotates off right away. This can
    be difficult to do, given ego, changes in road grade,
    and other things, but is needed to prevent burning
    people off too quickly.
