Where The Black Beacon starts and finishes

The Black Beacon starts at Bannau Brycheiniog — see the official site for the 2026 start venue. 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 The Black Beacon

Standard Training Window

20-24 weeks is the realistic window for a first 100-mile ultra, assuming you already have a marathon's worth of base behind you. The block that matters is back-to-back long weekends — a long run on Saturday followed by a second, slower one on Sunday — which builds time on feet and teaches you to run on tired legs without the recovery cost of one enormous day. Practise your race-day nutrition on every one of them; at this distance the stomach fails before the legs do.

Terrain Specificity

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.

The Taper Phase

Drop volume hard across the final three to four weeks — further out and steeper than a marathon taper, because a 30-mile training day costs weeks of recovery, not days. Keep some easy running and a little terrain-specific work in, but the goal is to reach Bannau Brycheiniog — see the official site for the 2026 start venue with fresh feet and a rested gut rather than one more long run in the bank.

Pacing Execution

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.

Fuel & Hydration Prep

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.

100-Mile Ultra Nutrition & Fueling Plan

2-3 Days Prior

A deliberate increase in carbohydrate over the two to three days before the race is the well-established approach at marathon distance.

Race Morning

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.

On-Course Fueling

Most runners take on carbohydrate every 30 to 45 minutes from about an hour in, alongside fluid at the on-course stations.

Post-Race Recovery

A mix of carbohydrate and protein in the hour or so after finishing supports recovery.

The Black Beacon Charity Places 2026

No formal charity-place scheme published — runners commonly fundraise for a charity of their own choosing.

Impactful Storytelling

Lead with your personal story — explain why the charity matters to you. Personal connection generates 3x more support than a generic link broadcast.

Social Campaign Milestones

Share key training milestones on Instagram (first 10-miler, peak week, race week) with your fundraising link in bio. Publicly thanking donors prompts secondary gifts!
