Where Windsor Half Marathon starts and finishes
Windsor Half Marathon starts at The Long Walk, Windsor Great Park and finishes at The Long Walk, Windsor Great Park, with Windsor Castle as the backdrop. We haven't been able to place those on a map accurately enough to show one — a pin in the wrong place is worse than no pin.
These are the start and finish points, not the route. Verus doesn't hold course files for this race, and drawing a line between two pins would be a guess you might end up training on. The official course map is the one to use: view it on the organiser's site .

Training Strategy for Windsor 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 The Long Walk, Windsor Great Park 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 tried-and-tested approach to topping up glycogen stores for a half marathon.
Breakfast should be carb-focused and eaten 2-3 hours before the start, using whatever you've already proven works in training.
On-course water/gel station details were not published at the time of writing — carry your own fuel if you have specific needs.
Within an hour of crossing the line, carbohydrate and protein together are what actually help you recover.
