Not strictly Strava, but this may be of interest to any cyclists, cycling fans, or just fans of endurance stuff generally.
In a couple of days my cousin is about to start a world record attempt at cycling the Pan-American Highway. It's 22,000km from Ushuaia in Argentina to Prudhoe Bay in Alaska. The current record is 117 days and five hours. Dean's aiming for 110 days.
He's doing it for charity, trying to raise GBP1million for Heads Together, a mental health awareness charity which seems to be similar to Beyond Blue. Sounds like they're about 1/3 of the way there.
Tracking will be available through the main website
https://www.pah18.com/, and plenty of background info is also on their facebook page at

They've put 20 months of planning, training and fundraising into this...it's already been a huge effort.
