About this skill

Race Strategy

When to use this skill

Use this skill when the request involves:

  • Planning race-day pacing strategy for upcoming events
  • Aid station tactics and efficiency protocols
  • Mental strategies for managing ultra-distance challenges
  • Gear setup and drop bag planning for races
  • Contingency planning (blisters, GI issues, getting lost, DNF decisions)
  • Pre-race logistics (race week protocol, course reconnaissance)
  • Post-race debriefing and tactical analysis

Core principle: "Train hard, race smart"

Philosophy: Tactical errors cost more races than fitness limitations. A well-prepared athlete with poor tactics will underperform; an adequately prepared athlete with excellent tactics often exceeds expectations.

Evidence base: Ultrarunning Training Essentials (Koop, 2nd Ed.), Training for Uphill Athlete (House, Jornet, Johnston)

Pacing Protocols

Fundamental pacing strategies

Even pacing (recommended for most ultra runners):

  • Maintain consistent effort (not speed!) throughout race
  • Measured by HR or RPE, not pace/speed
  • Best for: First-time distance attempts, conservative goal setting
  • Evidence: Minimizes glycogen depletion, reduces risk of bonking

Positive split (start faster, slow down):

  • Banking time early when fresh
  • Risk: Depleting glycogen too early, "blowing up"
  • Use cases: Very experienced, known course, aggressive time goals
  • Warning: 80% of ultra runners who positive split regret it at mile 60+

Negative split (start slower, speed up):

  • Conservative early, aggressive late
  • Lower risk of bonking
  • Best for: New to distance, challenging course, hot conditions
  • Challenge: Requires discipline to hold back when feeling good

HR-based vs RPE-based pacing

Heart Rate (HR) based:

  • Early race (first 25-30%): Stay below AeT (e.g., if AeT=160 bpm, cap at 155-158 bpm)
  • Mid race (30-70%): Allow drift to AeT+5 bpm on climbs, return to AeT on flats/descents
  • Late race (70%+): HR often decouples; switch to RPE
  • Advantages: Objective, prevents over-exertion early
  • Limitations: Heat/altitude/fatigue cause HR drift; less reliable late race

Rate of Perceived Exertion (RPE) based:

  • Early race: RPE 3-4/10 ("could talk in full sentences easily")
  • Mid race: RPE 4-6/10 ("conversational but requires focus")
  • Late race: RPE 6-8/10 ("can speak 3-5 words at a time")
  • Advantages: Works throughout race, accounts for fatigue/conditions
  • Limitations: Requires experience to calibrate

Hybrid approach (recommended):

  • Early race: Use HR to prevent overexertion
  • Late race: Switch to RPE when HR decouples
  • Crosscheck: If RPE feels much higher than HR suggests, slow down (fatigue/heat/altitude)

Terrain-based pacing adjustments

Uphills:

  • Steep (>10% grade): Power hike if hiking pace = running pace
  • Moderate (5-10% grade): Run if you can maintain conversational breathing
  • Gentle (<5% grade): Run, but don't force pace
  • Rule: If breathing becomes labored on uphill, slow down or hike
  • Poles: Use on sustained climbs >5% grade to reduce quad load

Downhills:

  • Steep (>10% grade): Control speed, use short steps, land midfoot
  • Moderate (5-10% grade): Let gravity assist, but don't overstride
  • Gentle (<5% grade): Run naturally, slight increase in pace acceptable
  • Warning: Quad damage accumulates; downhill speed in first 30% of race = quad death in last 30%
  • Eccentric loading: If quads burn on downhill, slow immediately (damage is progressive)

Flats:

  • Opportunity to "bank time" without excessive cost
  • Keep effort steady (RPE 4-6/10)
  • Focus on efficiency: cadence 160-180 spm, relaxed shoulders

Distance-specific pacing

50K (3-6 hours):

  • First 25K: Conservative (HR <AeT, RPE 3-4/10)
  • Middle 15K: Steady (HR ~AeT, RPE 4-6/10)
  • Final 10K: Push if feeling good (RPE 6-8/10)
  • Aid station time: 1-2 min max per stop

100K (8-14 hours):

  • First 40K: Very conservative (HR <AeT, RPE 3-4/10)
  • Middle 40K: Steady (HR ~AeT, RPE 4-6/10), allow HR drift on climbs
  • Final 20K: Survival mode (RPE varies, focus on forward progress)
  • Aid station time: 2-5 min per stop, longer if needed for recovery

100 miles (20-30 hours):

  • First 50 miles: Extremely conservative (HR well below AeT, RPE 2-4/10), "this feels too easy"
  • Mile 50-80: Steady grind (HR often decoupled, RPE 5-7/10), manage fatigue
  • Mile 80-100: Mental game (RPE 7-9/10), celebrate each mile
  • Aid station time: 5-10 min acceptable if needed, efficiency still matters
  • Night sections: Slow down 10-15% (reduced visibility, fatigue)

Aid Station Strategy

Time management protocol

Efficiency rule: Every minute at aid station = ~3 minutes of moving time to make up

  • Example: 5-min stop vs 2-min stop = 9 minutes lost on course

Target times by distance:

  • 50K: 1-2 min per stop (quick fuel, water, go)
  • 100K: 2-5 min per stop (fuel, check feet if needed, recover slightly)
  • 100 miles: 3-10 min per stop (fuel, recover, address issues), longer at crew-accessible points

In/out protocol:

  1. Approach (100m before): Decide what you need (water? food? gear change?)
  2. Arrival: State needs clearly to volunteers ("Fill both bottles, 3 gels, pretzels")
  3. Execute: While bottles fill, grab food, eat immediately
  4. Depart: Check you have everything, thank volunteers, GO

What to do at each aid station

Standard stops (no crew):

  • Refill hydration (both bottles/bladder)
  • Grab quick CHO (gels, bars, real food if tolerated)
  • Eat/drink WHILE at station (don't leave with food in hand to "eat later")
  • Quick body scan: feet ok? Chafing? Blisters forming?

Crew-accessible stops:

  • All of above PLUS:
  • Change socks if wet/hot spots detected
  • Apply lube to chafing areas
  • Change layers if weather changed
  • Restock personal nutrition from drop bag
  • Crew protocol: Crew should have gear ready, minimize talking, 5-min max

Major stops (e.g., halfway, mile 60):

  • More time acceptable (5-10 min)
  • Sit if needed (but set timer!)
  • Address issues: blisters, tape hot spots, change clothes
  • Eat real food if appetite allows (soup, potatoes, broth)
  • Mental reset: "I'm starting a new race from here"

Drop bag planning

What to include in drop bags:

  • Nutrition: Extra gels/bars you like (aid station may run out)
  • Hydration: Electrolyte tablets, spare bottle if worried about loss
  • Clothing: Extra layers (jacket, gloves, hat) + rain gear
  • Foot care: Spare socks, blister kit (tape, needle, lube)
  • Lighting: Spare batteries/headlamp, vest light
  • Emergency: Ibuprofen (use sparingly!), duct tape, safety pins
  • Mental: Motivational note to yourself, photo of family/goal

Drop bag locations (prioritize):

  • Halfway point (critical for gear swap, nutrition restock)
  • Before night section (lighting check, warm clothes)
  • Before final push (mental reset items, fresh socks)

Mental Strategies

Race segmentation

Break race into manageable chunks:

  • 50K: Think in 10K segments (5 segments)
  • 100K: Think in 20K segments (5 segments) or aid-station-to-aid-station
  • 100 miles: Think in 25-mile segments (quarters) or "sunrise to sunset"

Psychological trick: "I'm just running to the next aid station" (not "I have 60 miles to go")

Managing dark moments

Expect dark moments at predictable times:

  • Mile 30-40 (50K): Post-glycogen-depletion dip, often around 4-5h mark
  • Mile 50-65 (100K/100mi): Physical fatigue accumulating, night approaching
  • Mile 80-90 (100mi): Sleep deprivation, accumulated damage, "why am I doing this?"

Dark moment protocol:

  1. Acknowledge: "This is normal, expected, temporary"
  2. Physical check: Eat, drink, check pace (am I going too hard?)
  3. Mental reset: Break race into smaller segment ("just get to next aid station")
  4. Positive self-talk: "I've trained for this, I can handle this"
  5. Time limit: Give it 20-30 minutes; if still dark, reassess

When dark moment lifts (it usually does): Celebrate mentally, but don't surge pace

Positive self-talk protocols

Mantras to use:

  • "Relentless forward progress" (common ultra mantra)
  • "One step at a time" (when feeling overwhelmed)
  • "I've done harder things" (reference training or life challenges)
  • "This is temporary" (pain is transient)
  • Custom mantra (choose in training, use in race)

Avoid negative self-talk:

  • ❌ "I'm not good enough" → ✅ "I'm doing my best"
  • ❌ "I can't do this" → ✅ "I'm still moving forward"
  • ❌ "This is too hard" → ✅ "This is supposed to be hard"

DNF (Did Not Finish) decision framework

When to DNF (prioritize safety):

  1. Medical emergency: Severe dehydration, hyponatremia, heat stroke, injury requiring medical attention
  2. Time cutoffs: If mathematically impossible to finish within cutoff, save yourself for another day
  3. Severe injury: Continuing would cause long-term damage (stress fracture, severe sprain)

When NOT to DNF (push through):

  • General discomfort (this is ultra running!)
  • Dark moment (these pass)
  • Blisters (manageable with tape)
  • Fatigue (if you can still move forward, keep going)
  • "I'm slower than I wanted" (adjust goals, finish the race)

Decision protocol:

  1. Sit at aid station, eat/drink, address immediate issue
  2. Give yourself 10-20 minutes to reassess
  3. Ask: "Is this dangerous to my long-term health?" If yes → DNF. If no → continue.
  4. If DNF: Accept decision, don't dwell, learn for next time

Gear Setup

Mandatory gear (check race requirements)

Typical mandatory items:

  • Hydration (minimum capacity specified, e.g., 1L)
  • Nutrition (minimum calories, e.g., 500 cal)
  • Lighting (headlamp + backup, specific lumens)
  • Emergency (whistle, space blanket, first aid)
  • Navigation (map, GPS, phone)
  • Clothing (jacket, extra layer)
