Portsmouth Coastal Marathon Coaching
The Portsmouth Coastal Marathon is no cakewalk. It’s a full-on endurance test packed with everything the coast can throw at you – packed trails, unpredictable gusts along Southsea, and that shingle terrain ready to sap your legs of energy by mile 17. But you don’t have to let those challenges derail your race goals. We’re here to guide you with marathon coaching that tackles these hurdles head-on, helping you shave minutes off your personal best while staying injury-free.
We understand the marathon from start to finish: tempo runs that mimic the surges you’ll need in the race’s final stretch, pacing strategies for sections where the tide might slow you down, and fueling plans customized to your body’s unique carb demands. We don’t just hand you a plan – we build a system that supports you every step of the way.

Hitting Your Marathon Goal Starts with Science

We don’t guess when it comes to your performance. Our coaching approach is grounded in marathon-specific metrics and personalized progression. Here’s what we track and adjust throughout your journey:
- Heart Rate Zones: To prevent overtraining, we monitor recovery using heart rate variability and resting pulse metrics.
- VO2 Max Performance: Through custom interval sessions, we push your aerobic ceiling higher every week.
- Stride Analysis: Through gait evaluations, we eliminate inefficiencies that waste precious energy over 26.2 miles.
- Taper Period Optimization: Three weeks from race day, your mileage reduces strategically. We track glycogen depletion rates to ensure you’re fully fueled without carrying extra water weight.
Our goal is simple: consistent, measurable performance improvements you can feel with every mile.
Our Services: The Portsmouth Coastal Marathon Coaching plan
Training for a marathon with coastal terrain demands a different level of preparation. Portsmouth’s course includes trail sections where stabilizer muscles (think glutes, calves, and tibialis) do extra work. Neglecting these muscles can lead to premature burnout or injury.
Our coaching includes race simulations that factor in both mental and physical fatigue. This includes “back-to-back” training sessions where we replicate mile 20 conditions, forcing your body to adapt under controlled stress. Each week, you’ll undergo progressive overload training that improves endurance while preventing injury through structured recovery.
Customized Training Plans
Every runner has unique goals and limits. Your plan will focus on key areas like long-distance endurance, lactate threshold development, and cross-training designed to prevent overtraining. Expect weekly updates to your schedule based on your progress data.
Gait and Form Analysis
Faulty form leads to lost seconds and chronic injuries. Our high-speed video analysis helps refine your posture, stride length, and arm swing to make every movement as efficient as possible. Minor tweaks can add up to major race-time gains.


Strength & Stabilization Work
Runners who train only by running tend to overuse certain muscle groups. We incorporate low-weight, high-rep routines targeting underused areas like your gluteus medius and tibialis anterior. Strengthening these stabilizers reduces fatigue during uneven stretches of the course.
Nutrition Planning and Race-Day Fueling
Your performance hinges on fueling strategy. We develop personalized carb-loading protocols and in-race fueling strategies based on your body weight, sweat rate, and digestive tolerance. You’ll avoid the dreaded “bonk” by hitting exact hydration and carb benchmarks.
Performance Metrics and Feedback Loops
Through integrations with apps like Garmin Connect and TrainingPeaks, we monitor your splits, recovery, and fatigue scores daily. This allows us to make rapid adjustments, keeping you on track without risking overtraining.
FAQs
For most runners, peaking around 45-55 miles per week during the build-up phase is ideal. We vary this based on your running history and recovery capacity.
The taper should start three weeks out, with a 20-30% reduction in mileage each week. We also reduce intensity while maintaining race pace runs to keep your legs sharp.
We create a carbohydrate ingestion plan based on your body weight and race pace. Typically, athletes need 30-60 grams of carbs per hour through gels, chews, or drinks.
Choose a hybrid shoe that balances road and trail performance. We’ll guide you through testing options during your long runs to ensure optimal grip and comfort.
