How long is the Baked Potato route?

The redesigned 2026 Baked Potato covers 104 miles (167 km) with 6,902 ft (2,104 m) of climbing.

What is the Fully Loaded route?

Fully Loaded is a 118.3-mile (190 km) route with 7,779 ft (2,371 m) of climbing. It builds on the Baked Potato and adds the Copper Basin extension.

What is the Queen Stage Race?

For 2026 the QSR is a mix-and-match format — you can enter one, two or three stages in any combination. Wednesday is Harriman (Boulder Mountains singletrack), Thursday is Dollarhide (50-mile ride containing a 4.5-mile hill-climb TT with 30-second start intervals, optional finish at Frenchman’s Hot Springs), and Saturday is one of Tater Tot, French Fry, Baked Potato or Fully Loaded.

Is Rebecca’s Private Idaho self-supported?

Largely yes. Riders should plan to carry required nutrition, hydration and tools. Rest stops are expected but final 2026 support details, cutoffs and outside-assistance rules must be confirmed in the final Rider Guide.

Are there aid stations?

Known race-week anchor locations include Baker Creek (Wed start / kit pickup), Limelight Hotel (Thu kit pickup and start), Rotary Park (Wed awards and Brats & Bevies), Forest Service Park (Thu Be Good Foundation Party) and Champion Meadows (Fri expo, Sat start/finish and festival). On-course rest-stop distances and services for 2026 are published in the final Rider Guide — do not reuse 2025 logistics.

Is cell service available on course?

Cell service can be limited or unavailable across long backcountry sectors. Download the GPX offline and do not rely on streaming maps.

How should I fuel for the Baked Potato?

Starting point: 70–100+ g of carbohydrate per hour for trained athletes, weighted toward liquid and gel; hydration and sodium tuned to conditions and your sweat rate; caffeine only if practiced. Rehearse in training.

How much water should I carry?

Enough to cover the expected time between reliable water access, plus reserve. On Baked Potato that typically means 1.5–2.5 L on the bike between stops in mild conditions and more in heat, wind or on Fully Loaded.

How should I prepare for altitude?

Arrive early if possible, control early intensity, protect sleep, monitor fluid access and rehearse eating while climbing. Riders with cardiovascular, respiratory or medication concerns should discuss altitude with a clinician.

What weather should I expect?

Cool mornings, warmer afternoon sun, meaningful temperature swings between valleys and high points, high UV, exposed wind and the possibility of storms or rain. Check the seven-day forecast and race-morning update.

Can wildfire smoke affect the event?

Yes — late-season western wildfire smoke can affect air quality in the region. Check current AQI status in race week from official sources; do not use prior-year smoke details as 2026 facts.

What tire setup is best?

There is no single correct setup. Most riders run 40–45 mm tubeless gravel tires with reinforced casings and puncture-oriented pressure choices. Test on similar terrain — do not debut a new pressure on race day.
