Can you use it without Strava? E.g. runkeeper?

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.

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.

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!

Very cool! Should add a mode to tell me people if they _can_ run it.

is the time on a flat course?
