Training Fundamentals for a Sub 1:45 Half Marathon Pace

Achieving a sub 1:45 half marathon requires a strategic approach to training. You’ll need to build endurance, incorporate speed work, and understand the importance of long runs to maintain an average running pace of just under 8 minutes per mile.

Building a Solid Base

Before adding speed work and higher mileage, your foundation—built through easy runs—sets the stage for injury-free training. Begin with a schedule that comfortably includes running 30–45 minutes at a pace where conversation is possible. Aim for consistency over several months, gradually increasing the volume to build endurance.

Incorporating Speed Work

Speed work is key in teaching your body to sustain a faster pace. Introduce tempo runs—steady runs at a comfortably hard pace—to improve your lactate threshold. Also, short intervals slightly faster than your desired half marathon pace can boost your running economy and speed. Start with 4 x 800 meters and progress to longer intervals like 3 x 1 mile as you adapt.

Long Runs and Their Importance

Long runs extend your stamina, which is necessary for maintaining your sub 1:45 half marathon pace. Increase your long run distance gradually each week, peaking at 10-12 miles for a 1:45 target. These runs should be done slower than your race pace to build endurance without causing excessive fatigue. Your longest training runs are not just about physical conditioning but also a mental rehearsal for race day.

1:45 Half Marathon Pace: Race Preparation

A meticulous preparation plan is paramount to meeting your 1:45 half marathon goal. Detailed pacing strategies and proper recovery protocols enhance your performance capability for race day.

To achieve a 1:45 finish time, your average pace should be approximately 8:00 per mile. Begin by assessing your current performance and fitness level to set achievable splits. Utilize a mix of long runs, tempo runs, and speed work to condition your body to maintain this goal pace. Analyze previous races to adjust your pacing strategy, catering to anticipated race conditions. Consider integrating a pace band or running watch to monitor your splits in real-time during your race.

Tapering and Recovery

The final weeks before your race day should focus on tapering. Gradually reduce your mileage to allow your body to recuperate and recover. While tapering, maintain the intensity of your runs to keep your body primed. After your runs, prioritize recovery tactics such as stretching, hydration, and nutrition to repair muscles and replenish energy stores. Adequate recovery ensures you’ll arrive on race day well-rested and capable of executing your pacing strategy to achieve your goal time.

1:45 Half Marathon Pace: Nutrition and Hydration

Optimal nutrition and hydration are paramount for running a half marathon in 1:45. Your strategy should include tailored fueling before and during the race to sustain energy levels and careful post-race nutrition to aid recovery.

Fuelling Before and During the Race

To sustain a 1:45 half marathon pace, aim to start well-nourished with a focus on carbohydrates, the primary energy source for endurance activities. Consume a meal rich in complex carbs approximately 3–4 hours before the race. This could include oatmeal, whole-grain bread, or a banana. During the race, maintain your energy levels and prevent glycogen depletion by consuming carbohydrates in gels or chews, ideally taking one every 45 minutes to an hour.

Hydration is equally critical. Drink water regularly in the days leading up to the race. On the race day, have 16-24 ounces of water two to three hours before the start, with small sips as necessary 30 minutes before to avoid overhydration.

Post-Race Nutrition

After crossing the finish line, your recovery nutrition should aim to replenish energy stores and repair muscles. Within 30 minutes of finishing, consume proteins to repair muscles and carbohydrates to restore glycogen. A ratio of 3:1 carbs to protein is often recommended—snack on options like a recovery shake or a peanut butter sandwich. Hydration post-race is vital, too, so continue to drink water and consider electrolyte-replenishment beverages to restore any imbalances caused by sweating.
