Where Beacons Trail Marathon starts and finishes
Beacons Trail Marathon starts at Talybont-on-Usk, Brecon. 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.

Training Strategy for Beacons Trail Marathon
16-20 weeks is the target window for first-time marathoners; 12-16 weeks is solid if you're already maintaining a baseline mileage. Arrive with your longest run behind you in training, not on race day itself.
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 2-3 weeks while preserving short race-pace bursts. Arrive at Talybont-on-Usk, Brecon 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.
Marathon Nutrition & Fueling Plan
A deliberate increase in carbohydrate over the two to three days before the race is the well-established approach at marathon distance.
Eat a carbohydrate-focused breakfast two to three hours before the start, and stick to something you've already tested in training rather than trying anything new.
Most runners take on carbohydrate every 30 to 45 minutes from about an hour in, alongside fluid at the on-course stations.
A mix of carbohydrate and protein in the hour or so after finishing supports recovery.
