Here's some of the science on the topic: The time course of adaptations to exercise-heat acclimation. Within a week of acclimation, plasma volume expansion occurs and heart rate is reduced during exercise at a given work rate. Core and skin temperatures are also reduced when exercising at a given work rate, whereas sweat rate increases. Perceptually, the rating of thermal comfort is improved. As a result, aerobic exercise capacity is increased. Of note, the magnitude of these adaptations is dependent on the initial state of acclimation and the acclimation protocol (e.g. environmental conditions and exercise intensity).

Used the Outlander with three bottles on the bike to cross a desert in summer.

Oh? I have group 9F starting at 10:15 here https://www.capetowncycletour.com/events/the-cape-town-cycle-tour

Does anyone know if double laps are possible?

First generation Varia seat post mount Hey folks, I am looking for the quarter turn seat post mount for a first generation Garmin Varia radar. Can't find it at the LBSs. Cheers and happy 2025.

So, thanks again all for the great comments. I did a 12-hour solo night ride in the Cederberg, starting and ending at the Cederberg Oasis. Was a pretty magical experience, and the extreme isolation was really humbling. What a night though; some big skies. Saw this big boy on the road:

The crazies are few and far between 😉

Thats a great road to ride—fun to do it at night too (salut to the Munga Grit riders out there)

Desert Dash

Thanks all for your objective opinions—appreciated. Wishing you the best rides over the weekend!

Yeah—sensible words. I've done this loop solo during the day several times, but it sure does get lonely on Paarl rock late into the evening.

Hi folks, As the final prep for a big race next month, I'm hoping to ride through the night this weekend. I've got a 6 hour loop in the winelands (some of Bain's Kloof pass, some Paarl rock, skirting around Wellington and Paarl). I'm planning to start late afternoon, and finish 12 hours later in the early morning. Do you think its safe to do this? What should I keep my eyes open for?

Let me know if you've lost your Varia, I found one in front of Van Riebeeck park on Thursday morning.

Not cycling, but for illustrative purposes, race postponement done well: RD made the call; Postponement into good weather window; Automatic transfer to new date; or Free deferral to next year's event.
