Observed weather provided by The Weather Underground for the closet weather station for which data is available. Closest observation time to race start time is used, usually within 1 hour. If race start time is not known then 9:00 am local time is assumed.

The flow map plots all racers over time. Brighter and thicker areas represent more racers.

Racer icons can be added over the flow map:

Use highlight from the top toolbar or from the left side of the table to display highlighted racers in yellow.

Use the Division Icons selector in the map tools to display male or female icons for a division.

Adding a large number of racer icons may slow down the map.
