How We Rate Routes — The Difficulty Rubric

Why a rubric?

Most route ratings online are subjective — one rider’s “moderate” is another’s “terrifying,” depending on their bike, experience level, and how they were feeling that day. On this site every route, road, and trail is scored against the same five criteria. The grade comes from the numbers, not the mood.


The Five Criteria

1. Distance (max 4 points)

ScoreDistance
1 ptUnder 50 miles
2 pts50–150 miles
3 pts150–300 miles
4 pts300+ miles

2. Surface Type (max 4 points)

ScoreSurface
1 ptPaved, good condition
2 ptsPaved with rough or frost-heaved sections
3 ptsMaintained gravel (AK DOT graded)
4 ptsUnmaintained dirt, mud, or technical trail

3. Fuel Gap (max 3 points)

ScoreLargest gap between fuel stops
1 ptUnder 50 miles
2 pts50–100 miles
3 pts100+ miles — carry extra fuel

4. Remoteness (max 3 points)

ScoreCoverage & access
1 ptCell coverage most of the route
2 ptsSpotty or no coverage, towns nearby
3 ptsNo coverage, nearest help 50+ miles away

5. Hazard Factors (max 2 points)

ScoreHazards
0 ptsNo notable hazards
1 ptOne factor: wildlife crossings, seasonal washouts, or river ford
2 ptsMultiple factors or a serious river crossing

The Grade Scale

Total scores out of a possible 16 points map to five grades:

2Easy7–9 ptsLonger paved loop, some fuel planning needed
3Moderate10–11 ptsGravel sections, remote stretches
4Challenging12–13 ptsUnmaintained roads, significant fuel gaps
5Expert14–16 ptsTechnical terrain, extreme remoteness, multiple hazards

What the Rating Does Not Account For

The rubric scores objective, measurable criteria. It does not account for:

  • Weather — a Grade 2 road in rain or on early-season frost behaves very differently. All ratings assume reasonable summer riding conditions.
  • Rider skill or experience — the rubric is bike-agnostic and rider-agnostic by design. A Grade 3 on a 450 rally bike is a different experience than a Grade 3 on a loaded touring rig.
  • Seasonal condition changes — gravel roads in Alaska can change significantly after spring breakup or a heavy rain event. Every entry shows a Last Reviewed date so you know how current the information is.
