-Sleep aids: There is a time and place to be social, but sleeping on a flight or long car drive is a great way to add in some rest to your travel day. Dim the lights with a face mask, and tune out your neighbors with noise canceling headphones or earplugs. Sleep tablets are great for international travel, especially when you are trying to get on cycle with the time zone you are headed to.
-Compression: For car rides or flights, compression socks are great for increasing blood flow and preventing inflammation. With cramped seating and inactivity, these are critical for keeping your legs in a decent state for post-travel, pre-race preparation.

Once you have reached your destination, try to get out for a short jog or walk. In general, travel takes a lot out of you, so avoid any hard or long training sessions after you arrive. You should treat a travel day as a rest day, and focus on having a good meal, hydrating, and getting a quality night of sleep. Now is the time to direct your energy toward getting organized and focused for race day, knowing you did the best job you could to stay healthy during the travel.
