Turns a chat-designed run into a coached phone session
Overview
Pacing takes a running workout worked out in conversation and moves it onto a phone as a real session. The handoff happens through a card, a code, a deep link, or a QR scan, which removes the step of retyping splits into a notes app.
What can be requested spans single sessions and full plans: an interval set of 6x800m, a threshold tempo, something easy and long, or a multi-week build running from couch-to-5K up to marathon distance.
In the mobile app the workout becomes live coaching. Voice cues call each interval, flag pace drift, and give warning before a change. Heart-rate zone guidance is optional, and on supported iOS devices the live reading can come from AirPods Pro 3. Paces can be edited, the session saved or scheduled, and no GPS watch is required.

The chat side designs the workout and the phone side runs it, with audio cues standing in for a GPS watch.
Availability
Pacing: Run Coach & Tracker is listed in the ChatGPT apps directory only. Practicable LTD has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from Pacing: Run Coach & Tracker's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Practicable LTD, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
