Don't Stop Moving is a newsletter written for runners by a runner with 24 years of competitive and recreational running experience. The newsletter comes out monthly or thereabouts, with back issues periodically sent to the list. This mailing list discusses the sport of ultramarathoning. The focus is on bodybuilding and sports nutrition, athletic physiology and biochemistry, overall diet planning, and recipes. Low fat, high protein recipes preferred.
Supplement discussion is discouraged.
This list discusses aspects of biomechanics. You only need a newsreader and server and you can subscribe to thousands of lists and read a zillion contributions each day. Most of the discussions are informal, especially the sports oriented ones. The newsgroups you can access depends also on the Usenet server which supports your ISP, e.g. not all nl. The idea is that if you find an interesting newsgroup, via DejaNews for instance, you ask your ISP to put it on the server.
