Travel Pace as Risk Dial
Overview
Travel pace becomes a risk dial when faster movement also changes exposure, encounters, navigation failure, fatigue, or supply loss. The point is not realism by itself. The point is to make speed a meaningful choice.
Core Pattern
Every pace setting should change at least one of these:
- distance covered
- chance of getting lost
- encounter or event frequency
- hazard accumulation
- mapping or scouting quality
- rest or supply pressure
If pace changes only distance, it is usually not a real decision.
Cross-system Comparison
OSE daily travel baseline
OSE handles pace mostly through movement rate, terrain, and forced march. It is a conservative baseline: go farther, but pay with rest debt and greater strain.
DURF event-die pacing
DURF makes the tradeoff more explicit. Slow, quick, and fast travel change both hexes per watch and event-die pressure. This is one of the cleanest examples of pace directly controlling risk density.
Declared-speed dungeon variant
The movement-speed essay applies the same logic at smaller scale. Slow pace protects mapping and caution; fast pace trades detail and safety for reach; sprint pace converts movement into automatic hazard exposure.
Perilous Wilds role-based travel
Perilous Wilds distributes travel risk across moves like Scout, Navigate, Forage, and Make Camp. It is less about one speed number and more about which jobs the party performs to control the cost of movement.
Hazard-clock overlay
The hazard-system approach turns pace into clock advancement. Faster movement may fill exposure, attention, supply, or stability tracks quicker even when no immediate encounter happens.
Referee Procedure
- Offer 2 to 4 pace options such as careful, standard, forced, and desperate.
- For each option, state one benefit and one cost.
- Resolve travel in a fixed loop: declare pace, move, check navigation, advance hazards, resolve event, pay upkeep.
- Keep the pressure visible by naming the clock, debt, or event modifier being changed.
- Ask again whenever terrain, pursuit, weather, or dwindling supplies make the choice matter.
Variation Menu
| Model | Best for | Cost expression |
|---|---|---|
| Miles/day | Traditional wilderness travel | Rest debt, terrain penalty, getting lost |
| Hexes/watch plus event dice | Procedure-heavy hexcrawls | More events for faster pace |
| Speed bands per round | Dungeons or tactical exploration | Trap exposure, mapping loss, action loss |
| Hazard clocks | Survival play and hostile environments | Segments of exposure, noise, fatigue, or depletion |
Design Guidance
Use pace as the visible interface for hard choices. Players should be able to say, in plain language, "we go fast and accept more noise" or "we crawl and protect our mapping." If the tradeoff is not legible, the subsystem is doing hidden math instead of creating decisions.
Solo-play Utility
For solo use, pace is a good self-prompt because it forces a clear stance before resolving oracles and hazards. It keeps travel from becoming a blur of unevaluated random checks.
Practical Comparison Rule
Use OSE-style pace when you want minimal overhead, DURF-style pace when you want watch-by-watch tension, and hazard clocks when you want travel to steadily wound the party even in quiet stretches.
OD&D Concrete Reference: Miles Per Hour by Terrain
OD&D's Underworld & Wilderness Adventures gives movement as hexes per day (5 miles/hex). Converting to miles per hour clarifies short-range timing and shows terrain's drag on pace. Using a 12-hour daylight day as the baseline abstraction:
Ground and Water Movement (miles/hour)
| Mode | Clear | Woods | River | Swamp | Mountains | Desert |
|---|---|---|---|---|---|---|
| Man on Foot | 1.25 | 0.5 | 0.25 | 0.25 | 0.25 | 0.5 |
| Wagon/Cart | 1.5 | 0.75 | 0.5 | 0.5 | 0.5 | 0.75 |
| Draft Horse | 2.0 | 1.0 | 0.5 | 0.5 | 0.5 | 1.0 |
| Heavy Horse | 2.5 | 1.25 | 0.75 | 0.75 | 0.75 | 1.25 |
| Medium Horse | 3.25 | 1.5 | 1.0 | 1.0 | 1.0 | 1.5 |
| Light Horse | 4.0 | 2.0 | 1.25 | 1.25 | 1.25 | 2.0 |
| Raft | — | — | 4.0 | 1.25 | — | — |
| Boat | — | — | 6.25 | 2.0 | — | — |
| Merchant Ship | — | — | 5.0 | — | — | — |
| War Galley | — | — | 8.25 | 2.5 | — | — |
Flying Movement (miles/hour)
| Dragon | Griffon | Hippogriff | Roc | Pegasus | Broom | Carpet | Djinn/Air Elem. |
|---|---|---|---|---|---|---|---|
| 10 | 12.5 | 16.5 | 20 | 20 | 16.5 | 12.5 | 8.25 |
Design note: When fractional results occur (draft horse = 2.08 mph), round down to the nearest quarter mile. This table assumes 12 daylight hours; adjust ±2 hours for summer/winter if granularity demands it.
