1
00:00:00.140 --> 00:00:04.630
- I'm standing on the Oosterscheldekering,
the largest part of the Dutch Delta Works.

2
00:00:04.630 --> 00:00:06.430
It is a megastructure.

3
00:00:06.430 --> 00:00:08.860
An enormous dam, nine kilometres long

4
00:00:08.860 --> 00:00:12.060
with four kilometres of sluice gates
that can be closed

5
00:00:12.060 --> 00:00:15.690
to hold back extreme high tides
and stop the Netherlands flooding.

6
00:00:15.690 --> 00:00:19.990
It took a decade to build
and it is a rallying cry

7
00:00:19.990 --> 00:00:23.051
of human planning,
survival and achievement.

8
00:00:23.051 --> 00:00:25.600
And it is not what I'm here to talk about.

9
00:00:25.600 --> 00:00:27.770
There days ago, a forecast came in.

10
00:00:27.770 --> 00:00:29.130
A storm is going to hit,

11
00:00:29.130 --> 00:00:34.060
winds will gust up 120 km/h
on this barrier.

12
00:00:34.060 --> 00:00:36.700
And so a different rallying cry went up.

13
00:00:36.700 --> 00:00:39.930
Three words: "We kriehen sturm".

14
00:00:39.930 --> 00:00:41.360
A storm is coming.

15
00:00:41.360 --> 00:00:44.330
Because today is NK Tegenwindfietsen,

16
00:00:44.330 --> 00:00:47.240
The Dutch headwind cycling championships.

17
00:00:47.240 --> 00:00:49.700
Several hundred Dutch people
looked at this weather and said,

18
00:00:49.700 --> 00:00:51.620
"We're going to have a bike race in that".

19
00:00:52.770 --> 00:00:56.080
- The course is eight and a half
brutal kilometres.

20
00:00:56.080 --> 00:00:59.110
It's a serious event,
with permissions and everything.

21
00:00:59.110 --> 00:01:01.950
We have a limit of 300 participants.

22
00:01:01.950 --> 00:01:06.720
All the bikes are the same.
No gears, and just an ordinary brake.

23
00:01:06.720 --> 00:01:08.840
And it's a typical dutch bike.

24
00:01:08.840 --> 00:01:09.820
- Have you done it?

25
00:01:09.820 --> 00:01:10.880
- Yes, two times.

26
00:01:10.880 --> 00:01:12.380
- How difficult is it?

27
00:01:12.380 --> 00:01:17.163
- Very. I do triathlon in my spare time
and it's just as hard.

28
00:01:18.490 --> 00:01:23.150
- At high speed, up to 90% of the drag
on a cyclist is from air resistance.

29
00:01:23.150 --> 00:01:24.560
And I naively assumed,

30
00:01:24.560 --> 00:01:27.410
because it's been 15 years
since I've studied high school physics,

31
00:01:27.410 --> 00:01:29.730
that it'd be an equal
action-reaction thing.

32
00:01:29.730 --> 00:01:31.240
Double the wind speed, double the drag.

33
00:01:31.240 --> 00:01:34.270
But that's only true when
there's no turbulence.

34
00:01:34.270 --> 00:01:35.640
In a situation like this,

35
00:01:35.640 --> 00:01:38.950
the drag increases with the
square of wind speed.

36
00:01:38.950 --> 00:01:41.830
Double the wind speed,
quadruple the drag force.

37
00:01:41.830 --> 00:01:45.018
The difference between
cycling in a 15 km/h headwind

38
00:01:45.018 --> 00:01:50.018
and a 120 km/h gust is
64 times the added drag.

39
00:01:51.760 --> 00:01:52.593
- Why are you doing this?

40
00:01:52.593 --> 00:01:54.752
- I don't know. [laughs]

41
00:01:54.752 --> 00:01:55.870
I really don't know.

42
00:01:55.870 --> 00:01:58.586
- Do you regularly do bike races
and things like this?

43
00:01:58.586 --> 00:02:01.090
- No, just bike for fun.

44
00:02:01.090 --> 00:02:02.701
- How do you think it's going to be?

45
00:02:02.701 --> 00:02:04.980
- Hard! Very hard!

46
00:02:04.980 --> 00:02:06.520
- Succes!
- Dank je wel!

47
00:02:06.520 --> 00:02:09.440
- And sure, it's a good, weird
human interest story, right?

48
00:02:09.440 --> 00:02:12.070
People are doing a
deliberately difficult thing

49
00:02:12.070 --> 00:02:14.625
and hurting themselves just
enough that it's interesting.

50
00:02:14.625 --> 00:02:16.571
But this is a good place for it.

51
00:02:16.571 --> 00:02:19.630
Because not only are humans
literally pushing against the storm

52
00:02:19.630 --> 00:02:21.880
and saying, "we can beat you",

53
00:02:21.880 --> 00:02:25.030
they are on a physical
monument to doing just that.

54
00:02:25.030 --> 00:02:26.830
There's a big rock in the
middle of the barrier,

55
00:02:26.830 --> 00:02:28.847
with an inscription that translates as

56
00:02:28.847 --> 00:02:33.847
"Here the tide is ruled by
the wind, the moon and us".
