EVENT ALERT SYSTEM 

The TCS Toronto Waterfront Marathon will be using a colour-coded Event Alert System (EAS) at this year’s event to communicate the status of course conditions to event staff and participants leading up to and on race day. 

The levels range from Low (GREEN) to Moderate (YELLOW) to High (RED) to Extreme (BLACK) based on a variety of factors, including weather and event conditions. All event staff and participants should familiarize themselves with the Event Alert System colour indicators prior to the race, remain alert for directions from race officials, announcers and staff and take precautions to prepare for varying weather and event conditions on race day.
Event staff and participants should stay tuned to the current Event Alert System status via email, announcements and the colour-coded flags at Information Kiosk at the Expo prior to race day and on Race Day at the Help Desks in the Pre-Race/Post-Race Areas and Water & Aid Stations on course.
