# World Rowing Championships
This repository builds an Sqlite3 database with results from World
Rowing Championships.
|Year|Event |
|----|----------------------------|
|2010|WCH Karapiro, New Zealand |
|2011|WCH Bled, Slovenia |
|2012|2012 WSJCH Plovdiv, Bulgaria|
|2013|WCH Chungju, Korea |
|2014|WCH Amsterdam, NED |
|2015|WCH Aiguebelette, France |
|2016|WCHIE Rotterdam, Netherlands|
|2016|WCH Rotterdam, Netherlands |
|2017|WCH Sarasota-Bradenton, USA |
## Building
```sh
$ make
```
If you don't have Make available, you can also load `world-cup.sql` into
an Sqlite3 datbase to create the database from the CSV files in this
repository.
## Examples
### Fastest Races in a Year
Find the fastest races in selected boat classes for every year:
```sql
SELECT year,
class,
min(time_2000m) AS time,
team,
descr
FROM race,
crew
WHERE class IN ( "M8+", "W8+", "M4x", "W4x" )
AND crew.race = race.id
GROUP BY class,
year
ORDER BY class,
time,
year;
```
Result times are in seconds.
```

### Speed Difference between Light and Open Weight
Compare the fastest race for a boat class in a year between light-weight
and open-weight crews.
```sql
select
A.year,
A.class,
B.class,
printf( "%5.2f", (B.time / A.time - 1.0) * 100) as percent
from
(
select
year,
class,
min(time_2000m) as time
from
race
where
class in ("M4x", "W4x", "M1x", "W1x")
group by
year,
class
) as A
join (
select
year,
class,
min(time_2000m) as time
from
race
where
class in ("LM4x", "LW4x", "LM1x", "LW1x")
group by
year,
class
) as B
where
A.year = B.year
and "L" || A.class = B.class
order by
A.class,
percent
```
```

## Speed Differences Between Boat Classes
I've used this data to estimate speed differences between boat classes
for a [Reddit] question. I am estimating the 2k times for various boat
classes by averaging the fastest times found in several years. This
reduces the impact of conditions but assumes crews of comparable
fitness. Next I compute the factor between these times.
```sql
select class, avg(time) as time, count(*) as count from
(
select class, year, min(time_2000m) as time, descr
from race
where class in ("M8+", "M4x", "M4-", "M2x", "M2-", "M1x")
and time_2000m != ""
group by class, year
union
select class, year, min(time_2000m) as time, descr
from race
where class in ("W8+", "W4x", "W4-", "W2x", "W2-", "W1x")
and time_2000m != ""
group by class, year
)
group by class;
```

## Data Sources
The data in this directory was derived from
[World Rowing Championship Pacing Profile Project](https://github.com/danichusfu/rowing_pacing_profiles), which in
turn derived it from published race results. Compared with the original
data, the data here is slighly simplified.
