The Renegade Ultra Runner Plus 2 is a self-powered curved treadmill that lets you add magnetic resistance to every stride. It suits anyone who wants sprints, intervals, and sled-style conditioning from one machine. If you are weighing the best curved treadmill for mixed training, its resistance range is what sets it apart.
These are the Ultra Runner Plus 2 facts most buyers check first.

It feels responsive because the belt moves only when you drive it. No motor sets the pace, so each change in effort shows up in your next stride. Your top speed is limited by your output, not by a motor setting, which keeps sprint repeats honest.
Does a curved treadmill need electricity to run?
Not for the belt. Your stride powers it, the same motorless approach behind most of the Renegade Health and Fitness cardio line.
Most people need a few sessions to find their rhythm. This first-week progression keeps the learning curve short:
It changes what the deck trains. With no resistance added, the curve runs free for pure speed work. Adding resistance and magnets creates drag on the belt, so every stride takes more force at the same speed.
Renegade describes the range as running from free running all the way to a sled push. At the top of that range, the deck trains pushing power as well as running speed.
Is a curved treadmill harder than a regular treadmill?
Usually, yes. You create the belt speed yourself instead of keeping up with a motor, so the same pace asks more of your legs and lungs. Renegade adds that raising the resistance can burn more calories and add variety, though your actual burn depends on pace, effort, and body size.
The sprint coach. Athletes run short free-curve repeats, then close the session with heavy-drag pushes on the same deck. Set the Renegade Air Bike Unlimited Mag beside it, and the upper body gets its own conditioning station.
The hybrid-race athlete. Events that alternate running with sled pushes reward practicing the switch. Run a free-curve interval, raise the resistance, drop to the low bar, and rehearse the transition under fatigue.
Running and pushing need different hand positions. The upper bar suits upright running and walking. The lower bar sets your hands low and your body angled forward, the stance you use behind a sled. That low position is what turns high resistance into true sled conditioning.
Can people of different heights share one curved treadmill?
Yes, when the handlebars give them options. Renegade built the two positions to accommodate users of all sizes, which suits households and studios where several people train on one deck.

It pays off for buyers like these:
It is the wrong machine for some buyers:
At full width, the frame is wider than a standard 32-inch interior door, so measure every doorway, hallway, and stair turn on the delivery route before you order.
If another curve suits your room or budget better, compare our full self-powered treadmill lineup side by side.
Choose by resistance range and deck width first, then by budget. Here is how the Ultra Runner Plus 2 compares with two self-powered models we also carry.
| Detail | Ultra Runner Plus 2 | Ultra Runner | Sunny Smart Ultra |
|---|---|---|---|
| Price | $6,095.00 | $5,045.00 | $2,499.99 |
| Magnetic resistance | 6 levels | 4 levels | 8 levels |
| Running surface | 63"x19" (160cm x 48cm) | 63" x 17" | 59 x 17.7 in |
The Plus 2's premium over the Renegade Ultra Runner buys the sled-conditioning setup. If you only need a free-running curve, the Ultra Runner keeps the same commercial build for less.
On a tighter budget, the Sunny Smart Ultra manual treadmill is the value route. The Plus 2 earns its extra cost with a higher rated user weight.
Are curved treadmills worth the higher price?
They are for people who train hard and often. You pay more up front, but you gain sprint work and, with resistance, push work that a standard motorized belt is not built for.
Prepare the floor and the crew before freight day. Choose a level, protected floor spot before the truck is booked, and line up help for arrival, since a frame this heavy is not a one-person move.

What warranty covers the Ultra Runner Plus 2?
Warranty terms are not published on this listing. Contact our team before you order, and we will confirm the current coverage for you.
Does freight cost extra on this model?
Usually, yes. Renegade is not on our free-shipping brand list, so freight is quoted at checkout or on your invoice.
How much space does a curved treadmill need?
Start with the full-frame footprint, then add an open floor behind the deck for a safe step-off and room at each side to mount. Taping the outline on your floor shows the real footprint before you commit.
Can I return it if it is not right for me?
Yes, within 30 days, if it is undamaged, repacked in its original packaging, and used no further than testing. A 25% restocking fee applies, and return freight is on you, as set out in our shipping and returns policy.
Is it suitable for rehab or sore joints?
It is not sold as a medical or rehab device. If you are managing an injury, a joint condition, or a heart concern, get clearance from your physician or physical therapist before you train on it.
Does the Ultra Runner Plus 2 fold for storage?
No folding mechanism appears in its specifications, so treat it as a permanent fixture. Choose its spot with daily use in mind rather than storage.
