Why THRIVE after 40
Recovery slows. But your riding doesn’t have to. After 40 it takes longer to absorb hard sessions, muscle is harder to keep, and the same week of training lands differently than it used to. THRIVE bridges the gap, so every hard day lands on a day you can absorb it.
Riding after 40
In your 40s, recovery takes longer and hard weeks stack up faster. THRIVE reads it every morning and moves the hard session before it digs a hole.
Muscle and top-end power get harder to keep. Riders who added heavy strength work produced 7.8% more power in a 5-minute effort late in a long ride. THRIVE builds that work into your week.
Fitness matters more every year: people with elite cardiorespiratory fitness had 80% lower all-cause mortality than the least fit in a large 2018 study. THRIVE keeps you training consistently, at the right intensity.

“Once my masters riders trained to their morning recovery score, they stopped forcing hard days. They turn up fresher for the sessions that count.”

“MARCO kept me from blowing up at the wrong moment three different times across 28 hours of riding. Fueling reminders alone earned the subscription.”

Frequently asked questions
Do I need a bike computer or sensors?
No. HELIOS and the THRIVE app replace your bike computer, power meter and heart-rate strap. Your phone on the bars becomes the ride screen.
How does sizing work?
Pick your size if you know it (US 7 to 14). If you don’t, choose the free sizing kit: we send it first, you wear your closest size for 24 hours, confirm it in the app, and your ring ships.
Who is Marco?
MARCO is THRIVE’s AI cycling coach. Ask him by voice or text and he answers from your own sleep, recovery, rides and fuelling, and every change he suggests is shown to you first.
Do I need the THRIVE subscription?
The app plan is what turns the ring’s readings into your recovery score, training plan, fuelling and coaching. Your first month is included, then it’s $8.99/month. Cancel anytime.
How long does the battery last?
7–10 days per charge, depending on use. The travel charger in the box charges it over USB-C and holds extra charge, so you can top it up away from a socket.
What’s your return policy?
Wear it for 30 days. If it’s not for you, send it back for a full refund.
