Even though I don't have the experience of a lot of these guys, I just wanted to stop in and give you some words of encouragement.
1.) You went out there and tried. Better than those who just couch-ride.
2.) You had the guts to post on this forum which has its moments, but can also be shark infested waters at times.
3.) Ever after being dropped, you still tried to get back on and power through.
So good on ya. I'm sure if you focus on your training/endurance, you'll be able to hang with them soon enough! Cheers!
