I made myself a small challange once I hit level 30 that I wanted to keep my catches always higher than my stops.
As there is not much incentive of going past lvl 30 a part from a few power up and much more time between levels to acumulate dust and good iv mon I like to make my own game in some aspects like this one.
At this point I am level 35 half way towards 36, I have 16188 vs 15351 stops visited. Another small challange I have now after hitting 1000 km's on new year's is to get to 1000 gym trainings soon, I am at 975 but in my town there are only 11 gyms in total so is getting very hard for me ( I don't use any kind of trick like placing a low level mon on a gym I have just conquered to prestige against myself, or bubblestrat)
