Training Strategy for Cardiff 10K
6-10 weeks is a solid window for a 10K, whether it's your first or you're chasing a PB. Consistency and a weekly speed or threshold session matter more here than sheer mileage.
This is a largely flat course, so most of your long runs can mirror that — flat and steady, building time on feet rather than hill strength.
Ease off mileage in the final week, keeping a couple of short, sharp race-pace efforts to stay fresh. Arrive at King Edward VII Avenue, Cardiff CF10 3NS fresh, energized, and primed — not fit, fresh.
Lock in your target pace using the interactive splits calculator below — no official pacers are confirmed for this event, so a pace band on your watch is the more reliable option.
Test your race-day fuel and hydration plan on your long training runs, not for the first time on race day — check the Race Day Checklist below for what's actually on this course.
10K Nutrition & Fueling Plan
A modest increase in carbohydrate intake over the 2-3 days before the race is the usual approach for a race of this length.
Eat a carb-focused breakfast 2-3 hours before the start, and stick to something you've already tested in training.
A 10K rarely needs on-course fuel for most runners — water stations are the main provision at this distance.
Recovery starts with what you eat in that first hour — a mix of carbohydrate and protein is what the evidence supports.
