I can only imagine how bad Man on the Run is as I thought Matt Rendells The Death of Marco Pantani was poor. I track what I've read as I do like to re-read good stuff, against the Rendell book I have put - interesting but not well written, against his A Significant Other I have the comment great detail but too much wanky writing....guess I'm not a fan.
but surely nothing could be worse than Indurain - A Tempered Passion - I couldn't physically read that again and only made it to the end via skimming.
The best reads, so far for me, have been - The Hour by Michael Hutchinson and We Might as Well Win by Johan Bruyneel.
