Many parts of the ice are riddled with cracks.
This is definitely one of the most dangerous marathons in the world. Recently, the 10th Baikal Ice Marathon was held, attracting athletes from over 50 countries this year. These athletes possess iron-willed determination as they run the full 42-kilometer distance across the completely frozen surface of Lake Baikal — the world’s deepest freshwater lake (with a maximum depth of 1,580 meters) — enduring not only temperatures as low as minus 20°C but also the ever-present risk of cracking ice.
Sometimes the ice layer becomes very thin.
The Baikal Marathon is considered one of the top ten most challenging sporting events in the world. For participants, the bone-chilling northern winds and unpredictable weather changes are the biggest challenges. The weather at Baikal is highly variable — everything from strong winds and severe cold to bright sunshine can occur. The lake surface itself poses another major issue, as its thickness is uneven. Sometimes, hot springs beneath the ice and seismic activity can weaken the ice, even creating holes.
The race route is finalized just moments before the start.
The most critical issue before the marathon begins is safety. The event’s safety team closely monitors the course — they analyze satellite images to identify sections of ice that may be prone to cracking, and the final route is determined at the very last minute to avoid dangers caused by ice movement. Six food and water supply points are set up along the course.
Take a sip of vodka before you run.
Before the race begins, there is a very Russian-style ceremony where every athlete takes a small sip of vodka. Locals believe this ritual calms the lake and makes the race safer. The Baikal Marathon may be long, cold, and lonely, but those who have taken part all say it’s an amazing and magical experience.
