Here are some links that bear on the subject matter of these rambling discourses. If you know of a site that I should include here, do write in - remembering of course that this is a family-friendly blog that supports responsible shirtlessness (inclusive of jogbraed running) in both running and sports generally.
A) Shirtless Running or Sports
(Shirtless Robbie's intriguing, well-written blog covers a range of topics)
(b) Yahoo! Group
(Note: Yahoo! requires members of this group to be 18 or older. Personally, this seems harsh, and I see little reason for worry, but parents are advised of this restriction):
(It's pretty quiet at the moment here, but maybe new members willl liven things up).
B) Supporting (male) shirtlessness generally
(Note: Yahoo! requires members of these groups to be 18 or older. The groups are moderated and adult, problematic or offensive posts have been promptly removed in the past):
This lively and active forum discusses multiple aspects of what is called "the shirt-free lifestyle", which goes considerably beyond the subject matter of this blog.
Shirtless in the UK
Another friendly, UK-based forum "for any guys around the world who like to spend their time shirtless".
May 2015: First up, though I still try to put up blog content whenever I can, it has been easier to more regularly visit the the Twitterverse. Follow me at @barethomas10 and let's keep the shirtless running flag flying. Of course, the blog still attracts very interesting comments, and good discussion. Keep it up.
Second, in the years since this venture launched, and as shirtless running among women has gone increasingly mainstream, the term "jogbra" has clearly declined in use. I will thus prefer "sportsbra" henceforth - as has already been the case on Twitter, and in recent posts here.
I continue to welcome guest posts (sent to firstname.lastname@example.org) on any related topic, including from those who would discourage stripping to the waist. I am myself of course a fervent convert to the joys of running bare. But let all voices be heard!
