Race

What racers and reviewers say
- Slowtwitch: The Good, Bad and UglyRaced 2024 · article · Mixed
25th-anniversary edition: five-person rolling starts worked, but buoy rules crowded the second swim lap. Reworked bike added a quiet looped section through Jay with a fun descent; run trimmed River Road. Huge local crowd and praised staff, but Mortal Hydration ran out and residents are frustrated with athletes' road behaviour.
“We have to be better guests in the communities we visit.”
- Slowtwitch forum: Thank You IronmanRaced 2024 · forum · Positive
A 25-time Lake Placid finisher (14:26) describes a 1:18 swim, damp roads becoming dry on the second loop, light winds and a run/walk marathon. Family cheered him on and he intends this to be his last full IRONMAN.
- Slowtwitch forum: long IMLP race reportRaced 2010 · forum · Mixed
2010 athlete (171st overall, missed a sub-10 goal) whose swim was marred by sunscreen in his eyes; bike was conservative with stronger wind on loop two; run faded badly. Spectators in town were motivating.
“I knew what I was getting into when I started this.”
- Slowtwitch forum: IMLP race report (2007)Raced 2007 · forum · Positive
2007 racer (10:53, age-group placing 18th): 20 °C (68 °F) water, crowded mass start, fast shared bike pace, heat and wind on the second loop, and loud friends and family on the run. Praises Mountain Brook Lodge in Wilmington for friendly owners and quiet.
“I am an Ironman!”
- Slowtwitch forum: IMLP race report (2007, second)Raced 2007 · forum · Positive

Third IRONMAN: 1:11 swim in beautiful Mirror Lake but a crowded rolling start, a hilly bike with a nerve-wracking Keene descent, heavy rain on loop two, and loud spectators. She set a PB (11:42) and was on track for a Kona-position age-group result.
“it's not supposed to be easy!”

Analysis of 2025: slow swim, rain on the bike, cool temperatures; ten pro DNFs; yet several course records (Marquardt 7:50 overall, Loevseth first woman under 9 hours).

Analysis of the 19 July 2026 race: tough conditions on all three legs, slowest since 2019 for pros, though Van Riel set a new overall record of 7:41:57.
- Slowtwitch forum: More takeawaysRaced 2025 · forum · Mixed
2025 pro-race discussion focused on the broadcast: pixelated picture in a rural, rainy location and wrong split graphics. Little on the age-group experience, but confirms rain and a remote venue.
