The following email was sent by Tyler Hamilton on May 20. It explains his reasons for confessing to taking performance enhancing drugs and his hopes for the future, for both himself and cycling. Earlier, news broke in which Hamilton claims to have seen former teammate Lance Armstrong also take performance enhancing drugs.

Dear Everybody,

I hope this finds you all doing well.

First of all, sorry for sending this out as a group letter. If there was any way I could come visit each of you individually, I would. I hope we are together soon.

There's no easy way to say this, so let me just say it plain: on Sunday night you'll see me on “60 Minutes” making a confession that's overdue. Long overdue.

During my cycling career, I knowingly broke the rules. I used performance-enhancing drugs. I lied about it, over and over. Worst of all, I hurt people I care about. And while there are reasons for what I did -- reasons I hope you'll understand better after watching -- it doesn't excuse the fact that I did it all, and there's no way on earth to undo it.

The question most people ask is, why now? There are two reasons. The first has to do with the federal investigation into cycling. Last summer, I received a subpoena to testify before a grand jury. Until that moment I walked into the courtroom, I hadn't told a soul. My testimony went on for six hours. For me, it was like the Hoover dam breaking. I opened up; I told the whole truth, and nothing but the truth. And I felt a sense of relief I'd never felt before -- all the secrets, all the weight I'd been carrying around for years suddenly lifted. I saw that, for me personally, this was the way forward.

The second reason has to do with the sport I love. In order to truly reform, cycling needs to change, and change drastically, starting from the top. Now that I'm working as a coach, I see young people entering the sport with hopes of making it to the top. I believe that no one coming into the sport should have to face the difficult choices I had to make. And before the sport can move forward, it has to face the truth.

This hasn't been easy, not by a long shot. But I want to let you know that I'm doing well. The coaching business is more fun and fulfilling than I'd ever imagined, and Tanker and I are loving our Boulder life. I recently turned 40, and my friends threw the best 80's themed surprise party in the history of the world (hey, most of you were there!). Life is good.

Again, I just want to say I'm sorry, and that I hope you can forgive me. What matters to me most are my family and friends. I'm deeply grateful for all your support and love through the years, and I'm looking forward to spending time with all of you again, hopefully soon. My Mom and Dad always told me that the truth would set me free. I never knew how right they were.
