IRONMAN 70.3 Lake George

Arrive ready to move quickly from parking to the lake so you can warm up and calm your breathing before the start. If you’re seeded, get to your expected pack to avoid getting boxed in and to reduce hard surges in the first minutes. As the start gun goes, focus on a smooth, efficient rhythm for the first few hundred meters rather than sprinting for position.

You’ll swim 1900 m in the lake—conditions can vary, so treat sighting and line discipline as part of your speed. With the wind coming from the SW, expect waves or surface chop at times; keep your head position stable and let your body roll with the water instead of fighting every ripple. The water temperature varies, so if you feel “cold” early, settle into a consistent cadence and avoid overshooting intensity in the first quarter of the swim. Plan to leave the swim with enough control to start the bike strong; you’re not fueling during the swim, so keep hydration and carbs scheduled for the bike and run.

Set up your transition so you can move straight from swim exit to your bike with minimal searching. On the way into T1, focus on steady breathing and don’t rush the first pedal strokes—clear space, clip in smoothly, and get your cadence established. In the first minutes, aim to find a controlled effort that you can hold; the wind from the SW can make the ride feel different on each segment, so don’t lock into a hard pace too early.

You’ll ride 90 km after the 1.9 km swim, and with air temperatures ranging from 13.2°C to 24.4°C you can warm up quickly once you settle in. The SW wind at about 4 m/s is light-to-moderate, so expect it to influence speed more than it drains energy—still, be prepared for small changes in how the bike feels as you turn or ride into/with the wind. Fuel from the start of the bike: target 90 g carbs per hour with 750 mg sodium per hour and about 650 ml fluid per hour, and spread it evenly so you’re not “chasing” your targets later. If you feel your output climbing as the air warms, reduce stress by taking in more fluid and staying disciplined on effort rather than pushing harder to “catch up.”

Plan a fast, organized T2: get your legs moving immediately off the bike, but keep the first steps smooth rather than forcing pace. The first 5–10 minutes should feel like transitioning from “bike legs” to “run legs”—you should be building rhythm, not sprinting. If you’re prone to tightening up, loosen your stride early and focus on quick, relaxed turnover.

You’ll run 21.1 km after 90 km of cycling, and the moderate heat (13.2°C up to 24.4°C) means dehydration and gradual fade are the main risks. Keep the effort steady—use wind as a cue for pace: with a SW wind, there may be stretches where it feels easier/harder, so adjust by staying on perceived exertion rather than chasing the watch. Fueling should continue from your bike plan; as you approach late run, ensure you’re still taking in carbs and fluids consistently (don’t wait until you “feel” thirsty). If the air warms toward the upper end of the range, prioritize hydration earlier in the run to protect form and prevent early stomach stress.
