NexRex: AI Running Assistant

NexRex is built for runners with a race on the calendar and a goal they refuse to miss. From finding that race, to the start line, to looking back on the whole journey years later — Rex, your AI training assistant, remembers all of it. The longer you run, the better Rex knows you. Find your next race

Explore races at home and abroad, and lock in the one you're chasing Find runners going for the same goal — no more staring at the signup page alone

Train for this one, properly

Rex builds a plan around your goal race, from 5K to full marathon Overdid it or fell behind? Rex reshuffles the sessions ahead Remembers where you got hurt last time, and the race you ran best — and puts it into today's training Daily recovery and readiness: attack when you're sharp, hold back when you're not Log your meals and track nutrition, so every session is one you actually recover from

You're not training alone (NexRex is built for run clubs)

Join your club — training, communication, and races all in one place Your coach sees how you're doing, and Rex helps them stay on top of every runner — your coach is still your coach Rex matches you with training partners at your level, to run and race alongside
