1) everyone should have a watch. It doesn’t need to be a Garmin or Coros or anything, just so they know when 10 or 15 mins is so they can turn around
2) HIGHLY recommend everyone get a running water bottle. Something like this. https://a.co/d/058nL2y0
Plenty of options out there. Also if you go to Cadence tell them you are with Seton and they get a discount
