The theme this year is "Those who hope in the Lord will run and not be weary" (cf. Is 40:31) 

"Hope is precisely a new kind of strength that God instills in us, enabling us to persevere in the race, to see beyond present difficulties and to press forward to the goal of communion with him and the fullness of eternal life. If a beautiful goal exists, if life has an ultimate meaning, if nothing of what I dream, plan and accomplish will ever be lost, then it is worth the effort to keep walking, exerting ourselves, overcoming obstacles and fatigue, because the ultimate prize is magnificent beyond measure!" - Pope Francis
