About this app

Train for your next PR with a plan built around you.

NXT RUN creates a personalized, adaptive training plan for your goal race: enter your race date, distance (800m to marathon), current fitness, weekly mileage, and the days you can run. Your plan adjusts every week based on how you actually train.

MEET PACE, YOUR COACH BUILT IN
Ask questions, move workouts, and make any run easier or harder with one tap. PACE updates your paces after every run based on how workouts felt, so you are always training at the right effort.

WORKS WITH YOUR WATCH
Your next 7 workouts sync automatically to Garmin, Apple Watch, and COROS. Completed runs sync back and match to your plan. Strava supported too.

BUILT FOR RACING
Race time predictor that updates as you get fitter
Best efforts and trophies across distances: all time, this year, this plan
Grade-adjusted pace and detailed analysis on every run
Structured workouts: intervals, tempo, hills, long runs, strides

TRAIN TO QUALIFY
Chasing Boston? Annual Pro members who qualify while training with NXT RUN get $120 toward their Boston entry with the BQ Bonus (terms apply).

BUILT BY RUNNERS
NXT RUN was created by a husband and wife team: a 14:40 5K runner who has built running apps for 15 years, and a 2:59 marathoner with 10+ marathons. Real coaching experience, built into software.

I am confident that NXT Run offers the necessary plan, guidance, and feedback to effectively prepare for races. Having used NXT Run for 3 months (2 month 10k cycle and the first month of marathon training), I have experienced firsthand the benefits of its excellent UI and robust AI engine. Key features include: Dynamic scheduling, feedback, personalized paces, long-term view, and progress monitoring. I have full faith that guidance from NXT Run will be foundational to my marathon’s success.

This has been an amazing running app for me. The personalized training plans are tailored to my level, helping me to continuously improve. The feedback from the Run Coach GPT has been both encouraging and challenging. Definitely for runners who thrive on competition.

What’s new

• Fixed a snag where your Schedule could hang on the starting line right after you sign in. Now it loads first try, no restart needed.
• Smoother first run so a fresh install takes you straight to your training plan.
