70.3 in a Week
About this race
YOUR VIRTUAL 70.3 — NO START LINE. NO PRESSURE. JUST YOU VS. 70.3.
70.3 in a Week is a virtual half-Iron distance challenge for people who want to tackle a 70.3 — without a start line, a 3-hour ride, or the pressure of doing it all in one day. You take one week (plus a bonus week) to build it across the three events: swim 1.2 miles, bike 56 miles, and run 13.1 miles, spread out however you want.
Activities must be submitted within 7 days of completion, and your 70.3 in a Week is only complete once you've finished all three events: swim, bike, run.
You pick the date(s), choose the route, and go at your pace. Pool, bike trainer, and treadmill all count.
THE REQUIREMENTS
✅ Complete 1.2 miles of swimming, 56 miles of biking, and 13.1 miles of running or walking between January 18–24, 2027 — cumulative, in any order, at any pace
✅ Pool, bike trainer, and treadmill sessions all count
✅ Record every session in an app and submit the activity link or screenshot when you log it — finishes are due by Wednesday, January 27, 2027, 11:59 PM ET
HOW RESULTS WORK
Every session must be recorded in an app, watch, or platform — no manual, type-it-in entries.
