Hike and walk ratings consist of a number-letter code where the number is the distance and the letter is the amount of uphill climbing

	Grade	Elevation Gain
	1: Up to 6 miles 2: 6 - 10 miles 3: 10 - 15 miles 4: 15 - 20 miles 5: over 20 miles	A: Up to 1000 ft B: 1000 to 2000 ft. C: 2000 to 3000 ft D: Over 3000 ft E: Over 3500 ft

So a hike rated 2B means that the distance covered will be from 6 to 10 miles and the total elevation gain will be between 1000 and 2000 ft. A Mini-hike is 4 miles or less and has an elevation gain of 500 ft or less.

Backpack ratings consist of a number-letter code indicating length, elevation gain, and difficulty.

	Miles/day	Climb/day (ft.)	Travel
	1: up to 6 2: 6 - 10 3: 10 - 15	A: Up to 1,000 B: 1,000 - 2000 C: 2,000 - 3,000 D: over 3,000	T -Trail 1 - Limited/easy X-C 2 - Moderate X-C 3 - Strenuous/difficult X-C

So a trip rated 1B3 means that the most strenuous day will be as much as six miles of hiking, 1000 ft. of climb, and over strenuous to difficult cross-country terrain.
