What makes this plan different
Running two races across the same weekend means your legs have to perform twice — with one night's rest in between. The plan is built around that specific challenge.
Back-to-back weekends
From week 9, weekends include two runs: a longer run and a shorter recovery run the next morning. Your legs learn to go again the following day.
More volume than the Half
64 sessions versus 57 for the standalone Half Marathon. The extra sessions build the base and endurance a two-race weekend demands.
Magic Mile tracking
Periodic one-mile time trials show your pace improving across all 19 weeks, giving you a clear picture of progress heading into both races.
Who is this plan for?
Runners entering both races
You have entered the Princess 10K and Half Marathon and want a structured plan that prepares you for both — not just one.
Runners stepping up from the Half
You have already completed a half marathon and want to add the 10K the day before, with a plan that accounts for the combined effort.
Runners comfortable with back-to-back
You have done back-to-back weekend runs before, or are willing to build up to them across the 19 weeks.
Goal-driven runners
You want the most comprehensive plan in the app — 64 sessions across 19 weeks — and are committed to completing it.
Plan breakdown
Most weeks include three training sessions. Back-to-back sessions begin in week 9 and build to simulate race weekend conditions.
Weeks 1–4
Building the foundation
Establish consistent training with three sessions per week. Easy effort sessions focus on building the habit and recovering well between runs.
Weeks 5–8
Adding volume
Midweek sessions introduce cadence drills and hills. Long run distances begin to grow. First Magic Mile benchmark.
Weeks 9–13
Back-to-back begins
The long run is now followed by a shorter recovery run the next morning. This is where the multi-race plan diverges most clearly from the standalone half marathon plan.
Weeks 14–17
Peak training
Your hardest weeks. Back-to-back sessions are at their longest. The plan has built you specifically for this load.
Weeks 18–19
Taper and race weekend
Reduced volume to let your body rest and peak for race weekend. The 10K is on Saturday, the Half Marathon on Sunday.
Common questions
- What is the Princess 10K + Half Marathon multi-race plan?
- The Princess 10K and Half Marathon are two separate races held across the same race weekend — the 10K on Saturday and the Half Marathon on Sunday. This plan prepares you to complete both races consecutively, with a 19-week programme built around back-to-back training and progressive long runs.
- How is this plan different from the standalone Half Marathon plan?
- This plan has 64 sessions compared to 57 for the standalone Half Marathon. It includes higher midweek volume and a longer back-to-back training block to prepare you for running two races in two days. The taper is also structured to keep you sharp for the 10K without compromising the Half Marathon the following day.
- What are back-to-back training sessions?
- Back-to-back sessions are consecutive runs — a longer run followed by a shorter recovery run the next morning. They train your body to perform on already-tired legs, which is exactly what a two-race weekend demands.
- What is the pace requirement for the races?
- Current runDisney race policies require participants to maintain a 16-minute-per-mile pace. Always check the official runDisney event information before race weekend, as policies may change.
- Do I need to have run a half marathon before starting this plan?
- Not necessarily, but some running experience helps. If you have completed a 10K and have 19 weeks available, the plan builds you toward both distances. Complete beginners should consider starting with the 5K or 10K plan first.
- What if I am starting partway through the plan?
- Glass Slipper works out where you are in the programme and focuses your dashboard on the training still ahead. Earlier sessions remain visible for context but do not count against your progress.
