Training Strategy for Great Bristol Run Half Marathon
10-14 weeks is a solid window for a first half marathon; 8-10 weeks is enough if you're already maintaining a baseline mileage. Build your long run up gradually rather than jumping straight to race distance.
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.
Reduce overall mileage across the final 7-10 days while preserving short race-pace bursts. Arrive at Colston Avenue, Bristol 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.
Half Marathon Nutrition & Fueling Plan
A modest increase in carbohydrate intake over the 2-3 days before the race — not one huge pasta dinner the night before — is the conventional approach to topping up glycogen stores for a half marathon.
Eat a carb-focused breakfast 2-3 hours before your wave start, and stick to something you've already tested in training.
On-course water is provided, but gel-station brand details weren't published at the time of writing — carry your own fuel if you have specific needs.
Getting some carbohydrate and protein into you within an hour of finishing helps recovery start properly — Bristol's Harbourside has plenty of options near the finish.
