What is virtual racing?

Virtual racing is a category of racing in which participants do not run on a closed course. This means participants plot their own route and use their own recording device.

It has become known as the 'vegetarian bacon' of footracing. We're here to change that.


ISORACE III is ten miles long. Use Strava, How Far Did I Run, or a tape measure to plot your route.

10:00 BST

The race starts at 10:00 AM British Summer Time. If you're in a different timezone, prepare accordingly.

24TH APRIL 2021

The day Thutmose III ascended to the throne of Egypt in 1479 BC. Also the day of our race.

NEW Tyvek™ Self-Adhesive Bibs

Made from Tyvek™, a fully recyclable, flashspun high-density material, woven from polyethylene fibers. Abrasion resistant, waterproof, and extremely hard to tear. This is a bib that still looks good after the race.

They're also self-adhesive, so no need to mess about with safety pins. Just tear off the 3M backing and stick it right on.
