Potatoes are another nightshade. Nightshades are a common cause of joint pain and for some folks dropping them can even heal/minimize the symptoms of arthritis.
I find upping my intake of bone broth helps personally. (I have not cut out nightshades.)
I'd definitely lay off the biking for a bit once your race is done so you can heal!!
ETA: I don't know that I'd go grain free right b/4 a big physical challenge. Cutting grains can dramatically cut the amount of carbs you are getting (you can, of course, replace those carbs w/ fruits/veggies/tubers/nuts/seeds/etc, but it's actually hard to do) which could impact your energy levels during the transition (and maybe impact you during your race). Many folks who drop grains experience side effects during the first week(s)--even up to a month (sometimes low energy, feeling not optimal, etc). As w/ making any dramatic changes in your diet, going grain free can take a bit of time to adjust to (not for everyone, but it seems like many.) Also, many folks are used to running off of lots of carbs instead of fat/protein for the most part, so there can be a major adjustment there.
I LOVE being grain free, and would recommend it to anyone. When I dropped gluten though, a couple years ago, I had horrible withdrawl symptoms for a week--foggy head, dizzy, tired, etc. I just would be sure I didn't have anything too important to do when I was making the transition. If I were in your shoes, I might try some other things for the joint pain at the moment, b/4 your race, and try dropping grains once it is done if you're really interested in that.
Just wanted to add that!! Good luck figuring out what will work best for *your* body!
