My 1/2 Marathon Strategy as a Slow Starter
This Saturday (April 25, 2026) I'm running the Ohio health half marathon here in Columbus and unlike past races where I was merely trying to survive, this time I actually have a goal of finishing in approximately two hours and 10 minutes. I'm feeling reasonably confident about meeting this goal despite a rain forecast because I've been training pretty diligently for the past few months and know I can achieve the required pace. However, I’ve noticed anytime I'm out on a run I'm just a very slow starter. For the first maybe 2 to 3 miles my stride tends to be very short, I don't seem to be able to catch my breath, and generally speaking I just feel very uncomfortable.
Naturally I've been fretting about this in light of the ambitious desired finish time. Even just a few weeks ago I was on an 8 1/2 mile run with my training partner Charlie and once again during those first 2 to 3 miles I just did not feel good at all, but starting around mile 4 both my pace and comfort level increased significantly to the point that my pace towards the end of the run far exceeded the beginning! So over the weekend I spent some time yesterday talking to our good friend ChatGPT and it actually came up with a pretty good suggestion that's apparently called a negative split strategy. In a nutshell, ChatGPT said I can't hide the fact that I'm a slow starter and so I should just incorporate it into the plan.
For the first 3 miles I'm going to run a 10:30/mile pace then starting at mile four I'm going to run a 10:05 pace until I complete mile 8. Starting at mile 9 I'll increase pace again, accelerating to 9:50/mile pace and maintain it through the end of mile 11. Naturally at this point all bets are off but my guess is starting at mile 12 I'll be able to accelerate one final time to 9:30/mile pace through to the finish line. In summary my race pace will be:
- Miles 0-3: 10:30/mile pace
- Miles 4-8: 10:05/mile pace
- Miles 9-11: 9:50/mile pace
- Miles 12-13.1: 9:30am/mile pace
If I can meet this pace then my finish time will be approximately 2:11:22 (10:02/mile average), which would be a new PR (by far) for me.
Pre-race and In-race Diet
These days I'm also paying much closer attention to my diet, and want to be particularly diligent in the days ahead of the race. So 48 hours before the race I'm going to focus on eating grilled chicken, rice, vegetables, yogurt, granola, and fruit. The day before the race I'll have oatmeal, a banana, toast and peanut butter. For lunch I'll have a turkey sandwich and fruit, and then for dinner I'll have some pasta and chicken.
On Saturday the race starts at 8am. Around 6am I plan on having oatmeal, banana, and coffee. At 7am I'll have another banana.
During the race I plan on consuming a gel pack at the following times:
- First pack: start of mile 4
- Second pack: start of mile 8
- Third pack: start of mile 10
My gel pack brand of choice is the Gu pack, specifically the salted caramel flavor.
Attire
In past races I've worn a fannie pack to carry my phone and gel packs and absolutely hated it so this time around I bought a vest from Amazon. Nothing fancy, it's light and has a few pockets where I can store my phone and Gu packs.
