Introduction to Grand Tours
Grand Tours are the most prestigious and demanding stage races in professional road cycling. These three-week tours represent the ultimate challenge for professional cyclists and combine various stage types from flat stages to mountain finishes and time trials.
The three Grand Tours – Tour de France, Giro d'Italia and Vuelta a España – form the heart of professional cycling. Each lasts 21 days with two rest days and covers approximately 3,500 kilometers and more than 50,000 vertical meters. Only few athletes have won all three Grand Tours in their career.
Special Feature
Grand Tours are the only races in the UCI calendar with a duration of three weeks. They are therefore the longest and toughest tests in cycling.

Race Strategy and Tactics
Team Roles
A successful Grand Tour team consists of specialists with clearly defined roles:
GC Leader:
- Main protected rider for overall classification
- Receives maximum support from the entire team
- Must be strong in mountains and time trials
- Requires excellent recovery abilities
Domestiques:
- Support the GC leader in all situations
- Set pace on climbs
- Fetch water and food
- Sacrifice their own chances
Climbers:
- Specialized support on mountain stages
- Can attack for stage wins
- Protect leader on steep climbs
- Often also fight for mountains classification
Time Trial Specialists:
- Support in flat stages and TTT
- Set high pace on flat terrain
- Can win individual time trial stages
Race Phases
A Grand Tour is typically divided into three phases:
- Week 1: Positioning and avoiding crashes, sprint stages dominate
- Week 2: First mountain stages, GC contenders emerge
- Week 3: Decision in high mountains and final time trial
Time Bonuses:
At some stage finishes, time bonuses are awarded (10-6-4 seconds for top 3), which can be crucial for GC
Preparation and Training
Training Phases
Preparation for a Grand Tour begins 6-8 months in advance:
- Base Phase (6-8 months before): Building aerobic endurance, high volume at low intensity
- Build Phase (3-5 months before): Increasing intensity, specific climbing training
- Peak Phase (4-8 weeks before): Race simulations, altitude training camps
- Taper (1-2 weeks before): Reducing volume, maintaining intensity
Typical Training Week:
- Monday: 3-4 hours endurance at Z2
- Tuesday: 2-3 hours with climbing intervals
- Wednesday: 4-5 hours endurance with tempo blocks
- Thursday: 2-3 hours recovery
- Friday: 3-4 hours with sprint intervals
- Saturday: 5-6 hours long endurance ride
- Sunday: 4-5 hours with race simulation
Nutrition Strategy
Proper nutrition is crucial for Grand Tour success:
During the Race:
- Carbohydrate intake: 80-120 g per hour
- Fluid intake: 500-1,000 ml per hour
- Electrolytes: 300-600 mg sodium per hour
- Protein: 20-30 g immediately after stage
Daily Nutrition:
- Breakfast: High carb, low fat (3 hours before start)
- During stage: Gels, bars, rice cakes, isotonic drinks
- Recovery: Carbs + protein within 30 minutes
- Dinner: Balanced with vegetables and quality protein
Famous Grand Tour Winners
Triple Crown Winners
Only seven riders have won all three Grand Tours in their career (not necessarily in the same year):
Only two riders have ever won all three Grand Tours in the same year: Eddy Merckx (failed in 1974) and Christopher Froome (attempted in 2018). The "Triple" in the same year is considered nearly impossible.
Records
Most Grand Tour Victories Total:
- Eddy Merckx: 11 victories (5 Tour, 5 Giro, 1 Vuelta)
- Bernard Hinault: 10 victories (5 Tour, 3 Giro, 2 Vuelta)
- Jacques Anquetil: 8 victories (5 Tour, 2 Giro, 1 Vuelta)
Youngest Grand Tour Winner:
