Once the balloons are virtually launched (see launch sequence on the Eco Racing homepage (www.ecoracing.co), they are subject to a simulated flight pattern based on the actual weather conditions such as the prevailing wind speed and current temperature. This simulation uses an advanced computer-modelling programme linked to Google maps and a commercial weather data supplier, Aeris. By clicking on ‘balloons’ on the race homepage, you will see the leading 100 balloons listed. The information shows straight line distance travelled in kilometres from the launch point, plus the balloon’s latitude and longitude.
