Set my race goal, but don't make that goal my master.
A fast time or PB isn't my sole aim. If I PB great, if I don't great, finishing is my main goal. In trying to achieve anything great it's likely I'll have more disappointments than people will see, but it's about continuing with good spirt whether I win or lose.
Don't listen to the ego or other people's opinions.
Focus on what I can control and work hard in training. Although I've completed a 60+ mile week. That's not a guarantee of anything come race day.
Be relaxed and face all the challenges of race day. I can't control the external elements but I can control how I react to them.
Fast marathons are the result of long and solid training buildups. Although I'm not looking past this race, this is part of that buildup as I approach the races for 2018.
I've learnt from Tokyo, there's things outside of my control, but I can choose to have a good attitude and enjoy the great opportunity to run the Chicago marathon.
