My wife and I are wanting to try and train for a triathlon sprint. We have swam some and would be able to do that part and we will not have a huge problem running a 5k but neither of us have a road bike for training or to do the race in. It seems like a lot of money to spend to just try something out. I'm 6'3" and cannot seem to find a used 60 cm bike on Craigslist or Facebook marketplace for less than $200. Will an academy road bike that costs $200 be fine or is there actually something about spending $500 or more on a bicycle? I don't have any experience with bikes and only have a mountain bike buts it's too bulky to ride 13 miles comfortably.
