Run Kent Half Marathon Route Map & Elevation Profile
Starting at The Judd School, Brook Street, Tonbridge, Kent TN9 2PN and finishing at The Judd School, Brook Street, Tonbridge, Kent TN9 2PN. Total elevation gain is not published for this event, and Verus does not estimate one.
Is Run Kent Half Marathon flat?
No consensus — some runners describe it as undulating with "plenty of ups and downs," others call it flat by comparison to other Kent courses. Independent estimates conflict too (one route tool suggests around 207m of gain, another around 123m), so there's no single reliable figure — expect a genuinely mixed, gently rolling course rather than pancake-flat or seriously hilly.

Training Strategy for Run Kent 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 Judd School, Brook Street, Tonbridge, Kent TN9 2PN 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 over the 2-3 days before the race is the conventional approach for a half marathon.
A carb-focused breakfast 2-3 hours before the 9:00am start, ideally something already tested in training.
On-course aid stations are confirmed but not precisely located — carry your own fuel if you rely on gels.
Within an hour of crossing the line, carbohydrate and protein together are what actually help you recover.
