Today, I did 75 km and it was quite hard to keep going at ~55 km so it does not happen right in. I checked the height of my saddle, my leg angle is about 150 degree and the cleat is properly aligned with the front of the knee (using a string with a lead). I tried different cleat position but I guess the injury was already done so it didn't help much. Is this the symptom of a specific thing? Big deal breaker... it's like in the front of the left knee, always the same leg.
Sounds like you didn't change your shoes or cleats. If you were riding a lot last year, without pain, and now you have pain of recent and abrupt onset, you should look very carefully at what changed last Tuesday. Did you make any adjustment? Was this a significant step up in your riding distance?
I recently had knee pain after a long (for me) ride, the second longest ride I'd ever done. I found the problems was that during the ride my seat post had slipped down almost a cm. I need a fair amount of leg extension, and that was enough, over the longer distance. So look hard at what changed last Tuesday. And you'll need to recover, now that it's injured, as you said.
