I just joined two months ago myself, so I'm new too, but so far everyone on tennisblr has been lovely. I've also delved headlong into Fedal, and there is a ton of great content you can sink your teeth into. I'll put everything I know in this long post, but tennis mutuals feel free to jump in with more recs!
Tumblr peeps
@tennisandlife is another awesome blog to follow, even though they stopped posting in 2020. I literally spent 3 hours going through their archive, there is SO MUCH quality Fedal content.
Books on Federer and/or Nadal
Rafa: My Story by Rafael Nadal and John Carlin. A must-read for any Rafa fan. Rafa in his own words, through 2011. What I love most is getting Rafa's insights into his own game, his approach and preparation for matches, his journey.
The Master: The Long Run and Beautiful Game of Roger Federer by Christopher Clarey. Probably the most comprehensive Federer biography to date, published in August 2021. Clarey traces the development of Federer from boyhood to 2020 in an attempt to figure out the how and why of Federer. Along the way you get a lot of insights into Roger's game, his team, but Roger himself still remains somewhat inscrutable and untouchable. Not unlike the man himself. If you contrast this to the confessional approach in Rafa, where you actually get into Rafa's head, you could make the argument that the distance in The Master is due to the difference between biography vs autobiography, but I also think it's very fitting for Rafa's personality vs Roger's. Still, given the challenge of the task, Clarey does a commendable job in attempting to unravel Federer. A must-read for any Roger fan.
Roger Federer and Rafael Nadal: The Lives and Careers of Two Tennis Legends by Sebastian Fest (2018). This was the third book I read, and I assumed that it would retread much of the content from the other two books, but I was pleasantly surprised. Sure, the book rehashes many of the key moments in their rivalry, such as Wimbledon 2008, but it also covers a lot of the behind-the-scenes things that the other two books don't--things like the ATP Players Council and Roger/Rafa's political fallout in 2011-12, Rafa's knee injuries and treatments, how the anti-doping measures impact players, etc. A good supplement that gives an interesting view into the challenges of being a professional tennis player.
I haven't read the following yet, but I'm hoping to get my hands on them soon:
(I love Rafa, but you can probably guess which half of Fedal comes out on top for me)
Fanfics
I'm not going to recommend specific fics, but rather favorite writers on AO3. Any Fedal from these writers is awesome, you can't go wrong.
Mystivy - everything from mystivy is the best. I just finished reading the "Joy" series, which is simply beautiful. Only parts 1 and 2 are written; part 3 looks like it was never posted so it's technically an incomplete series.
emungere - you know emungere, so no need for me to explain how amazing her writing is. "Wild Card" is the fic I needed when I first dived into Fedal. You must be logged in on AO3 to view emungere’s tennis rpf.
Serenade - mostly ficlets, but each one is incredibly insightful and makes you go "oof." “Tennis Is Not A Game You Play Alone” has my favorite line from any Fedal fic: Rafa met his gaze, dark eyes unreadable. "I would rather lose to you," he said, "than win everything in a world where you never exist."
eliane - I haven’t actually read any of eliane’s fics but I’ve seen multiple recs, so this is next on my to-read list. Must be logged in to read on AO3.
louise_lux - I also haven’t read any of louise_lux’s solo work, but I read the joint fics she co-wrote with emungere and they were fuckin’ hot. Also on my to-read list.
Video
Strokes of Genius - feature-length documentary of the 2008 Wimbledon final. You can find it on YouTube (here's one link but not sure it works. I watched it on these links: part 1, part 2, part 3) Also the Rafa and Roger bonus features.
Rafael Nadal Academy - 4-episode documentary series on Amazon Prime. Takes you into the daily life and operations of Rafa’s tennis academy in Manacor. You meet the staff there and follow the stories of 8 students who are pursuing their tennis dreams. And of course you see Rafa in the episodes too, but it’s primarily about the academy. I wish they would do a season 2.
The bazillion videos from 2017, 2019, and 2022 Laver Cup on YouTube. Fedal played doubles in 2017 and 2022, and were supposed to play doubles in 2019 but Rafa got a wrist injury.
Roger Federer: Everywhere Is Home: documentary of Federer’s 2019 Latin America exhibition tour, produced by ESPN: Vimeo
Roger Federer: The Reunion: documentary of the 2020 Match in Africa charity exhibition match with Rafael Nadal. Available for rent or purchase on Vimeo
NBC/Credit Suisse documentary about the art installation project that Roger was part of: Portrait of a Champion
Rafa Nadal Academy’s Instagram has tons of videos and photos of Rafa as well. Here’s a video about when Roger visited the Academy for its grand opening in October 2016. You can find other videos from the grand opening on YouTube, like the press conference and speeches.
I want to say that there’s a 20-min or 40-min documentary about Federer vs Nadal in the 2017 Australian Open produced by AO Films or something like that, but I can’t find it now. :( Maybe other tennisblr folks can help? Found it!
YouTube also has highlights or full matches online. I recommend 2008 Wimbledon final, 2017 Australian Open final, and 2019 Wimbledon semifinal, and their associated press conferences/interviews.
Miscellaneous
Rafa’s diary from his old website (copied by someone on LiveJournal for posterity).
I read somewhere that Rafa wrote a couple of tour diaries or blogs for the ATP tour way bay when as well, but I can’t find them. Tennis mutuals, any help? Is that the same as the link to Rafa’s diary from his old website?
Rafa Nadal Fans website - I haven’t really looked at this, but at first glance it looks like a ton of Rafa content.
Stalk Follow them on official social media accounts for Roger, Rafa, Severin Luthi, Rafa Nadal Academy, etc.
Tons of interviews and articles from major publications such as New York Times, Sports Illustrated, GQ, you name it. Just google “Roger Federer cover story” or “Rafael Nadal interview.” There’s also the tons of interviews and articles in Spanish, French (L’Equipe), German (Blick, Tages-Anzeiger), etc, some of which you can translate on Google Translate.
