cycling Outdoors is generally hard unless you have spec like Fiesta Island was a great place to train I used to train at Fiesta Island because for people who don't know where that is in San Diego it's where all with the time trial bike races were and it's just a 7 kilometer Loop that you can ride on without lights or any like there's no traffic or anything that gets in your way but for the most part like I wouldn't be able to do Zone 2 outside here in Austin it's just it's too hilly and there's too much traffic and it just it it it fits and starts
