Early season injury?

Few weeks ago, just after I had started to ramp up cycling to work and running, I started getting a new kind of pain in the groin area of my left leg when running :( 

It started as just some minor discomfort but as I didn't really take it easy (my bad), it became painful to run without adjusting my running position. To my defense, it wasn't painful enough to make me stop when running and usually the discomfort will be worst until I got warmed-up enough ... Walking was slightly painful but when cycling, the pain was not there but I could definitely feel a little something in the groin/hip area.

At first, I though it was coming from my adductors but then the pain moved a bit along the thigh and to the hip, glute and Rectus femoris. As the result, I have been taking it easier, especially with the running with last week being totally off.

I resumed running last night (with an easy 8km) and the specific discomfort that I was feeling before when running wasn't there. My legs were pretty sore, however, from Sunday's morning 80km ride, so I'll have to see how that goes during the 2 other planned runs for this week ... However this morning, after my usual 22km ride to work my left hip and glute are slightly painful :-\

Run to Stanley Park (30k)

Saturday run to our now usual long distance target went pretty well. This time around, I didn't forgot to drink my espresso two hours before we got going, however I followed the tips from Allen Lim, and decided to not take any food during the run itself and only rely on my usual energy drink (minus the Chia seeds) just to keep my blood sugar level elevated (and replace my electrolytes).

Since the infamous wall lives around the 30km mark for most people, I was curious to see if I will run into it (didn't ran into it last time I ran a marathon either) ... And, It wasn't the case as I feel pretty energetic all the way (with an average pace of 5:10/km). Obviously the 2 days of moderate carbo-loading plus a bagel (with peanut butter, chia seeds and one banana) 3 hours before the start of the run was enough to fuel me throughout the run. As a measure of precaution, I did carry a bunch of dates ...

Two days prior to the run, I started feeling one of these weird pains at the top of my left calf, not unlike other pains I have felt recently on my calfs. So I wore my compression bands (on both calfs) as prevention most of the two days and, of course, during the run (as usual). In the end, I didn't feel any calf pains during the run (nor after), just some mild knee pains. However, starting yesterday afternoon (so 24 hours after the run) my left thigh started being painful (rectus femoris?) when at ease. I cycled to work this morning and didn't feel anything special. Anyhow, I'm supposed to run this late afternoon so I'll see how it goes ...

Overall, I have to say that since I started wearing compression bands on my calfs when running, my calf pains have pretty much vanished. I know there's a lot of debate on the effectiveness of them, but it appears to be working for me ... or that's just a coincidence.
