I am new to cycling. Haven't ridden in years. I'm in the market to buy a bike. I'm going to be riding mainly 15 to 20 miles per day and want to work my way up to half centuries and centuries eventually. I'm going to be riding mainly hwy and some gravel roads. Should I opt for a hybrid or road bike? Looking mainly at Giant and Trek brands. Would like to stay under 1000.00 for my first bike but would like for it to last for awhile before I upgrade. Is it possible to get a bike for that price to meet my needs or not? Thanks for any input. If you have a different brand of bike you'd like to recommend, I am open to suggestions. Thanks for all your help.
