base, you can start your training with Week 13 of the . If you start right away (June 19-26), the training schedule will take you right up to race day. To make sure you’re well rested for the big event, limit all your walks for Week 25 to 20 to 30 minutes each, even though the official schedule says otherwise. It’s definitely a good idea to acclimate to the higher altitude of Boulder (or whatever the conditions will be at the event you’re participating in) by doing some pre-event walks in the mountains. Just make sure you take it easy and don’t make these your long walks. It’s also a good idea to arrive in Boulder a few days before the half-marathon so your body acclimates and you feel good during the event. Good luck!
