You take something to read when going to watch bobsleigh world cup races - there is some downtime and even allowing for time to move somewhere else along the track you can squeeze in at least 30 minutes worth of reading between heats.
Improvement for this year: bought a cheap stylus to poke the PW with so that I can turn the pages and keep my gloves on in -10c temperatures
(last year I just took a pbook with me for that reason).
