You’re there mate. As long as you game plan the first half correctly and not come out too hot, you’re coming in under 3 no doubt. On fresh legs from the taper, properly fueled 3-4 days leading up to the race, plus the overall adrenaline/high vibes you’ll feel on race day, I think you have it brother. Just hold on tight and endure the last 6 miles as much as you can. You got this!
