My personal best is wrong or isn't recognized – what can I do?

Trait tries to detect your personal bests automatically from your imported and recorded activities. That's harder than it sounds – and not always reliable.

Why a personal best can be wrong

At their core, watches and services only deliver raw data to Trait: GPS coordinates and timestamps. From these, Trait calculates pace and segments itself. If the GPS signal jumps briefly, it looks like a sprint. Example: in a 21 km run with a GPS jump, Trait wrongly detects two or three extremely fast kilometers – and with them a personal best you never actually ran.

Can the personal bests list be corrected?

Honestly: not at the moment. An incorrectly detected value stays in the list, and we can't change it for you either. We know that's unsatisfying – and we're happy to take the request on board.

Is it actually the prediction you're concerned about?

Often, behind a "wrong personal best" there's actually a prediction that doesn't match your current form. For that, there's "Enter current performance" (Pro): Open the Stats page and tap the Feelgood Pace box. At the bottom you'll find the Predictions ("Today you could run the following time …") and below that, in the fine print, the note "Are these estimates wrong? Improve them by doing an assessment run or entering a current performance". There you enter a real, recent performance, e.g. 10 km in 45:00. This improves your prediction – but doesn't change the personal bests list.

What the feature is not

"Enter current performance" is meant to improve your prediction – not as an archive for your personal bests from years gone by. The feature plays a minor role in Trait.

Personal bests don't change your paces

Your training paces come from the Feelgood Pace, your ratings in the checkout, the heart rate analysis and the assessment run. Personal bests play no part in this. The tip sometimes given in the past – to enter your goal time as a personal best so the paces fit – is therefore wrong; please don't do it. If your paces don't feel right, you'll find the right levers in the "Paces & Zones" category.
