Find your race.
Find your people.
Pacers, crew, marshals, coaches, organisers — and the runners who depend on them. Long-distance running, properly organised by the people who live it. GPX-verified courses, Strava-linked trust, no payment middleman.
Bield is just getting started — and we're building it with the running community, every day. Every race we add, and every pacer, crewer and organiser who joins, makes the next runner's day better.
Pacers, crew and coaches — the people who get you to the finish.
Long-distance running is a team sport. Match with a pacer who knows your race, line up crew you trust at the aid stations, and find a coach to build toward your goal — all in one place.
Splits, crew points and pacer hand-offs — for ultras, not 5Ks.
Drop your race GPX, set a target time. Bield reads the elevation and gives you realistic splits, where to put crew, and where pacers take over — all computed in your browser, nothing uploaded.

Set a distance for flat splits, or drop a GPX for elevation-adjusted ones. Pacer hand-off points and crew-reachable checkpoints come from your route — dynamic with an account.
Open the full calculator →Personalised fuelling, weather & pacingA generic table guesses. Your account tunes the plan to you — a preview of the variables that come into play:
Design the whole course, on the map.
The organiser's course workspace. Draw and snap a route to real trails, drop checkpoints, marshal posts and aid stations, and watch a live Bield difficulty score update as the course takes shape — GPX import and multi-stage races built in.
And everything on the map is the same record as its detail page — move a marshal here and it moves on the Marshal Posts screen, and back again.
One race. Two sides. One place.
Bield connects what organisers build with what runners need — the same race, five stages, one shared thread from the first plan to the finish-line photos.
Design the course in Route Studio, set up the race and its aid stations.
Find a race, check its difficulty, explore the 3D course.
Recruit marshals and volunteers, plan aid stations and logistics.
Build your kit list and fuelling plan, line up pacers and crew.
Manage entries and the applications coming in.
Enter the race and apply for the help you need.
Live marshal tracking, first-runner and sweeper tracking.
Follow your splits, crew hand-offs and fuelling reminders on the move.
Publish results and race photos.
Get your photos and highlight reel, leave a review, find your next race.
Can it do it? Yes — here's how.
The specific stuff people actually ask, answered straight.
How do I know if I'll be fit enough — and what I'll need?+
Every race shows its Bield difficulty score so you know what you're taking on, and Bield builds you a personalised kit list and an hour-by-hour fuelling plan tailored to that course.
Can I find people to help me pace, crew or marshal?+
Yes — post what you need and browse pacers, crew and volunteers, then handle their applications all in one place.
Can I plan the whole trip, not just the run?+
Yes — the race, where to stay, the logistics, your pacers and crew, applications, and even your finish-line photos afterwards, all in one place.
Can I see a race's aid stations and what food they have?+
Yes — every aid station can list its food, and flag whether it's vegan, vegetarian, gluten-free and more, so you can plan around it.
Will I be able to see the course before race day?+
Every course has a 3D flythrough and downloadable GPX, with checkpoints, crew points and pacer hand-offs all marked.
Can an aid station list its food?+
Yes — and each station can be tagged vegan, vegetarian, gluten-free and more, so runners can plan around it.
Can I see who's at each marshal point?+
Yes — live marshal tracking, plus simple "first runner passed" and "sweeper passed" tracking as the race moves through the course.
Can I recruit and manage marshals, pacers and crew?+
Yes — post the roles you need, take applications, and assign people to points on the map.
Can I design the course myself?+
Yes — Route Studio lets you draw and snap the route to real trails, drop checkpoints and marshal posts, and see a live difficulty score as it takes shape.
What happens after the race — results and photos?+
Handle your results and race photos (auto-tagged to each runner by bib number) in the same place you built the race.
