The Frankfurt-Mainz-Mannheim race course
The course used for the 1910 Frankfurt-Mainz-Mannheim cross-country air race started at
the Griesheimer Exerzierplatz, around five kilometres west of central Frankfurt.
It was
initially intended that there would be a control point at the Wiesbadener Rennplatz
(racecourse), around six kilometres southeast of Wiesbaden, but close to the event it was
decided that it was unsuitable for landing and that it was cancelled. This meant that there
was only one control point and optional landing ground, at the Mainzer Sand military
exercise grounds, on the sand dunes around five kilometres west of central Mainz. It was
indicated by a tethered red-and-yellow balloon with a diameter of two metres.
The finish was initially proposed to be at the Mannheimer Rennplatz, at the Luisenpark
around two kilometres east of central Mannheim, but it was decided at a late stage to move
it to the Exerzierplatz, around two kilometres to the north. The finish line was indicated
by a large cross marked on the ground.
The straight-line distance of the final course was around 91 kilometres, but it was
expected that most pilots would follow the Main and Rhine rivers to simplify navigation,
resulting in a course length of 105-110 kilometres.
All the airfield installations at the different locations were temporary and only used for
this single event.
