Cleanse Retreats

“I used to be too heavy to do something weight bearing, so I didn’t run, as a result of it’d be too painful on my knees.

However most individuals who haven’t been right here don’t notice that 70% of Hong Kong is nation parks, a hilly panorama, and an in depth path system,” mentioned Blumberg, who acquired bored with understanding on the gymnasium and had a revelation when he discovered a path system existed.

I went to run The North Face 100k – Singapore in September 2010 and got here in third. I by no means anticipated to podium. So, I went from a work-hard, play-hard way of life to an ultrarunning habit. For a beginner who was grossly overweight and a borderline alcohol addict 10 months prior, it was outstanding for me,” mentioned Blumberg.
A Knack for ‘Slams’
Subsequent, he ran the 2011 Vibram Hong Kong 100k, ending in tenth place.

“I’d journey and do a race on the weekend, then fly again to Hong Kong to work. I mainly did three 100ks over three successive weekends in several international locations.

That’s once I mentioned, ‘Ah, I appear I get well fairly nicely,’” mentioned Blumberg, who then experimented with a vegetarian food regimen for 18 months, which helped to cut back the irritation in his physique and enhanced his restoration. There have been restricted vegetarian meals choices the place he lived on the time, so he didn’t preserve the food regimen.
Creating the Hong Kong 4 Trails Extremely Problem
Additionally in 2011, Blumberg was deciding what to do over the Chinese language New 12 months, a four-day nationwide vacation. Often, he and his spouse, Paper, would journey, however they determined to remain dwelling in Hong Kong that 12 months.
He began finding out 4 long-distance trails that encompass Hong Kong and an concept percolated to mix the 4 right into a single goal.
The 4 trails had been the 70k Lantau Path, the 78k Wilson Path, 50k Hong Kong Path, and the 100k MacLehose Path.
“I requested round if anybody had ever run these 4 trails in 4 days. Individuals mentioned, ‘No, after all not, it’s inconceivable and can’t be finished.’ I mentioned, ‘Let’s strive.’ The overall is 298 kilometers roughly, and 14,500 meters of elevation achieve. To my shock, I managed to complete them: one a day. I used to be joyful I completed however I used to be additionally disillusioned, as a result of it was too straightforward,” mentioned Blumberg.
The unique grassroots four-trail occasion grew to become often known as the Hong Kong 4in4 Problem, which has grown in reputation and is held yearly throughout Christmas.
The next 12 months, in 2012, Blumberg tinkered with the format, mixed the 2 shortest trails, and completed all 4 trails in three days. Six runners began and three completed.

Fuji in Japan, which can also be 100 miles lengthy. “I felt that the longer distances suited me higher, as a result of I’m not very quick however I appear to compensate by being cussed and never quitting and making an attempt to hold in there,” he mentioned.
In 2013, he modified the format of the four-trails problem once more, rearranging the sequence to make it logistically wise for a nonstop format, which made it much more tough.
“I didn’t run it, as a result of in that third 12 months, it grew to become common, and I wished to direct it and I’ve finished that ever since. I haven’t been capable of run it once more, but. It’s a totally self-supported occasion, there are not any extra course markings, and 0 help is allowed. It’s on path, and there are path indicators.

The format takes runners within the reverse course of the unique format: the 100k Maclehose Path, 78k Wilson Path, 50k Hong Kong Path, and the 70k Lantau Path.
“Lantau is the final path and it’s a loop round Lantau Island. The beginning and end is at Ferry Pier. In entrance of the pier is a inexperienced colonial publish field that it’s important to kiss to designate the end of the problem,” mentioned Blumberg.
For the Hong Kong 4 Trails Extremely Problem and the Hong Kong 4in4 Problem, a course map and GPX file will not be offered. Impressed by the Barkley Marathons, Blumberg additionally throws in variations annually, including a bit extra issue. One 12 months, no trekking poles had been allowed and one other 12 months, no audio gadgets had been allowed.
General, Blumberg sees internet hosting the occasions as a solution to give again to the ultrarunning neighborhood.
“I don’t need these to be elite occasions. I would like all kinds and variety of individuals,” mentioned Blumberg, and added, “I’ve been eager to get extra ladies to take part and tried numerous makes an attempt like selling the occasion to ladies and researching feminine ultrarunners and alluring them or asking them to think about taking part. One 12 months, I had a rule, if a male participant could make two profitable referrals to ladies, then he can get a spot. I’m happy to say, on this 12 months’s Hong Kong 4 Trails Extremely Problem we had eight ladies take part and eight males, so it was 50/50 gender participation,” mentioned Blumberg.
Blumberg additionally enjoys sponsoring athletes to journey, masking their flights and resort, and race in high-profile occasion. “For different occasions, I’ve supported much less privileged athletes within the area together with from Thailand and the Philippines to return to Hong Kong to compete within the Vibram Hong Kong 100k and The North Face 100k – Hong Kong. Having the ability to afford it, it’s my solution to give again and to assist in giving publicity to individuals which are athletically gifted and do nicely domestically however don’t have monetary means to journey internationally,” he mentioned.
