Race Planner - GPS Analysis & Nutrition for Ultra/Marathon

What is a Race Planner?

Race Planner is a tool for detailed race course analysis and creating optimal race strategy. It analyzes elevation profile from GPS track, calculates pace/power distribution accounting for terrain, plans nutrition points, and determines optimal energy expenditure strategy for achieving the best result.

How to Use the Race Planner?

Upload GPX or FIT file of race course (download from race website or create in Strava/Garmin Connect). Enter your target indicators (pace, power, HR) and physiological parameters. The planner will create a detailed plan: pace distribution by kilometers, nutrition points, carbohydrate consumption, finish time forecast accounting for all course features.

Race Planner Features

• Elevation profile analysis and normalized load calculation for hilly courses
• Optimizing pace/power distribution by segments for even load
• Planning nutrition strategy: when and how much carbohydrates to take during the race
• Finish time and energy expenditure forecast accounting for terrain and weather conditions

Frequently Asked Questions About Race Planner

How does the planner help improve results?

Optimal effort distribution can improve results by 3-7% compared to even pace on hilly terrain. The planner shows where to slow down on climbs (avoid overload), where to accelerate on descents (time savings), where to take nutrition (prevent 'hitting the wall'). This is especially critical for marathons, triathlons, and ultratrails.

What data is needed for accurate planning?

Minimum: GPX track of course, target time or pace, body weight. For accurate calculation, desirable: VO2max, lactate thresholds (LT1/LT2), FTP (for cycling races), body fat percentage, carbohydrate consumption rate. More data means more accurate plan, but basic planning is possible with minimal input.

Can it be used for triathlon and duathlon?

Yes, the planner supports multisport events. For triathlon, upload separate tracks for bike leg and running segment, specify parameters for each discipline. The system will calculate effort distribution accounting for accumulated fatigue and optimal nutrition strategy for the entire race (Ironman, 70.3, Olympic distance).
