London Marathon Events

TESS support London Marathon Events with the safe delivery of several mass participation events throughout the year, including London Marathon start, Swim Serpentine and Royal Parks Half Marathon.

Since 2017 TESS have been working year on year to support LME introduce expert measures to improve the experience of those participating in their events.

Each LME event comes with its own unique and complex set of challenges for the TESS team to navigate, including the size of the event sites, routes through central London, 50,000+ participants, and tight build and break times.

At London Marathon, the team are faced with a 3 hour build window between the closure of busy central London roads and participant arrival, while at Swim Serpentine supporting the client with decisions relating to weather and water can become essential to the event going ahead.

Over the years, TESS have worked hard to identify areas of improvement, advise the client and work alongside them to implement creative changes. These improvements have been widely varied, including applications to local authority, improvements in weather monitoring procedures and changes to site design.

No year is ever the same and TESS look forward to continue working with LME to keep their events running, swimming and cycling safely.
