There’s quite a bit of gps disagreement over the average grade. My wahoo Bolt pegged it at 7.5%, whereas some others come in around 6% and the official Strava segment has it at 4.2% which I have to believe is too low. I’ve arbitrarily labeled as 6.5% for this site :)
This is a great climb, but my preferred way up this side of Ratlum is Barbourtown just because there is less traffic and the road is narrower and therefore more interesting. Having said that, this version has a nice crazy 20% gut punch towards the end, so touché Wright Rd!
