Trans Iowa is a self-navigated, self-supported, 300-plus mile gravel road event. Held in late April primarily on Iowa gravel roads.
The Trans Iowa course is a 320-340 mile loop that approximates what it would take to cross the State of Iowa at any given point West to East. The course changes every year. There are time limits to checkpoints, which, if not met, mean you are out of the event. The ride is self-supported, guided by cue sheets, and the route is secret until the day of the event. It is approximately 95% gravel road, 5% pavement.
The Trans Iowa is started at 4:00am in the morning on a Saturday, (usually the last weekend in April), and is run straight though Saturday, all night, into Sunday, and usually ends at 2pm Sunday afternoon.
There is a Pre-Race Meeting which is mandatory and is held the night before the event.
