I totally see your point (many competitive runner never posts to Strava, anyway). I'm working on a Garmin integration now, so that should be available soon. It looks like runkeeper only has manual activity exports, so I'd have to provide a way to allow for manual activity uploads, too, which is doable!
Back in the day I had my running PB’s and current times in an Excel (financial ey) comparing them with the line of the world records. Worked pretty spot on. Better 5k leads to a proportional gain on the longer runs. Never beat the 50% slower mark on any of my times. Nowadays with VO2-max, HRV and other measures personal predictions must be getting easier. Although my Garmin watch thinks I’m world class VO2-max, which is a joke.
What did the line represent? It’s always surprising how predictable it is to estimate people’s race times given what you know about their fitness. That said, about 10% of the time someone surprises you with a time you wouldn’t expect.
I was working under the hypothesis that my fitness would generally predict my performance when compared to the world record. Turns out for +50% of the worlds top speeds, this works pretty well. New hypothesis would be that specialization occurs way below +50% of the worlds speediest.
My Garmin times are also a joke, which is why I created getfast! (To be clear though, Garmin makes incredible watches, and their predictions have gotten a lot better in the past year . . .)
As an early adapter, I can testify that the prediction has been spot-on for 6 of my half-marathons. It gives me a realistic goal to chase, allows me to adjust my training, and provides good feedback on the training.
Would recommend people to check it out!
Interesting. I’d always wondered how my shorter training distances might translate to an actual marathon length race!
is the time on a flat course?
Yes, a flat course on a cool day! There's a link to some details on the models here: https://getfast.ai/models

Strava is just so horrible to use with all its gamification and social aspects. For me running is a solitary pursuit with significant mental side-benefits, but Strava is trying to tell me about someone I don't know running a particular stretch faster or slower than me, trying to egg me on to go faster or further or out-run someone locally etc. Do not like. RunKeeper is just a simple tracker with none of the bullshit, so I prefer it.
