There are numerous runs on Strava starting from the same location for the same route into Brockwell Park, they're absolutely consistent and repetitive. This differs prior to the summer of 2020 but everything since then starts in the same place with the exception of one run in January in Streatham (I've included a couple of examples but there are many). One thing to consider is that the runs are almost exclusively on weekends, meaning she may have left from a friend or partner's address however I'd imagine that unlikely, again dude to the consistency.
I use Strava and I am fully aware of the privacy radius but with the sheer number of runs starting at the same location, I'd say the likelihood that her home address is on Craster Rd and therefore her intended destination on the night she went missing. Unless of course she secretly made a change of plans for food or to visit a friend but the implication of friends is not in the public domain and shouldn't be speculated on. Frankly this is all speculative and folks ought to wait until more information is released to piece this together, frankly we know next to nothing. The police will clearly be gathering CCTV evidence for beyond what is known online. Just wait people. Everybody is now just flailing.
