I've been testing things out and running pretty regularly this cycle (3-4 times/week). For the most part, no issues. So, I don't think it's a direct trigger for me. I did for the first time though, have an attack on Sunday; 10km into what ended up being a 13.5km run. I've never had a hit while running. Have had a few right after running. So, this was a first. I had zomig with me, but decided not to take it, to see how continuing to run would work out (another first for me). I did find that it never really ramped up to a full intensity hit. Only to around a kip 2. And went away after about 20 minutes (15 of which were running + 5 as a passenger in the car heading home). My attacks usually last an hour. So, this was really interesting for me. I had read the posts about aborting with physical activity. But I really never could have imagined being able to do it. Will definitely be doing more experimenting with this one.
Side note - not sure if it's the verapamil (now on 120mg x 3/day); but I do find my runs feel harder than they do when out of cycle. And I've been running at a much easier pace too.
