Out into barren land

Not much haze but our scenic ride was very barren, dusty and hot, i like to ride on dry land so i don't have to wash my bike much when i get home later. Today the ride was much longer and extremely fast paced,with a group more than 25 people everyone ride at different pace resulting gap and broken to several group...some got lost, some too fast, some too slow and some seem to be wondering into the wild in their own adventure. I huff and puff my way up and down the hill chasing my rival, at night when i sleep i can feel my legs kinda heavy.
