Please remove all chance elements from race events

Im really tired of the blocks that appear and disappear in the last level of ultra always costing me while im ahead the win, im also tired of the blocks in multi making me lose due to many setbacks+at the end I just get a setback and grab it many times then finally someone else comes along and on their first try they win the event. I mean the events are in the race door, not chance so im not sure why the chance is present here a race is a competition of getting through but the chance should be removed from each of the events imo. As well as the gnomes nesr the blind maze in ultra since they spawn randomly.
