"The Cruelest Miles" is indeed THE book to read on the
subject. And there is also "The Adventures of Balto: The
Untold Story of Alaska's Famous Iditarod Sled Dog", by
Patricia Chargot. While the latter is written for a younger
audience, the research is impeccable, and there are some
great historical photos in it.

a book i have recommended to a lot of people is called "The
Cruelest Miles" by Gay and Laney Salisbury (who sighned my
copy) Very long but very very acurate and reliable.

Balto Claw...there was no race in the real history. Dog
teams were simply called for, and assigned to different
sections of the route. The race is a purely fictional
aspect of the Balto cartoon.

Further, there was never a race to Anchorage. You're confusing the Serum Run with the annual Iditarod, which runs from Wasilla (a suburb of Anchorage) to Nome. The Serum Run ran from Nenana (a town near Fairbanks) to Nome...over a much different route.

yes, that is the true vershion. In 1925 kids in nome got a
hight fever that was called Diptheria. They din't have
enouph medicine for every body, so they had a meeting to
have a race to acorige. so balto raced to acorige and got
the medicine and brought it back to nome.

I can help you Saba. Just PM me. I haven't read the books
you are referring to, and so I don't know their content or
its accuracy. However, I know a pretty good amount about
the real history, and would be very happy to help you.
