Switchback: Offline Race Guide

Your ultra's race manual is a 30-page PDF you skimmed once and can't search at mile 60 at 2 AM. Switchback turns it into a field guide on your phone: the aid stations, cutoffs, pacer and crew rules and driving directions you actually need, laid out so you can take them in at a glance. And it keeps working when the signal disappears.

Guides are built race by race and checked against each race's official information. Find a race shows what's ready. Don't see yours? Tap Request guide and we'll move it up the list.

One guide for the whole team - Runners: know every aid station, cutoff and climb, and build a pace plan - Pacers: where you join, the pacer rules, and your runner's notes on what they need from you - Crew: a driving plan with every stop you can reach, in order, with estimated drive times - Runner view for planning; Crew view for everyone supporting, pacers included

The race manual, made easy to absorb - Every aid station with mileage, cutoff time, crew access, pacer, drop-bag and medical flags - An elevation profile of the whole course with crew stops marked - Race rules distilled: pacer limits, crew rules, packet pickup, start details - Important race updates shown at the top: cancellations, course changes and new rules are flagged as soon as the guide is updated

Plan your pace - Enter a goal time and see a target arrival time and cutoff cushion at every aid station - Mark real arrivals and the plan re-projects from your actual pace - Per-station packing lists and notes for the runner, and private notes for the crew

Share with your pacer and crew - Send your plan to your pacer and crew with a QR code or a link. No account needed.

Built for the field - Works fully offline after your first load. Open a race once on wifi. - One-tap directions to every crew stop in Apple Maps or Google Maps (download offline maps for the area before race day) - Large tap targets and a clean, high-contrast design for daylight and night
